Question: At camp Wonka, there are 96 campers.  Two-thirds of the campers are boys, and the remaining one-third are girls.  50% of the boys want to toast marshmallows and 75% of the girls want to toast marshmallows.  If each camper gets one marshmallow to toast, how many marshmallows do they need?

The girls make up one-third of the campers, so there are 96 /3 = <calculate step="1">96/3</calculate><result step="1">32</result> girls.
The boys make up two-thirds of the campers, so there are 32 + 32 = <calculate step="2">32+32</calculate><result step="2">64</result> boys.
There are 32 x 75% = <calculate step="3">32*75*.01</calculate><result step="3">24</result> girls who want to toast marshmallows.
There are 64 x 50% = <calculate step="4">64*50*.01</calculate><result step="4">32</result> boys who want to toast marshmallows.
They need 24 + 32 = <<24+32=56>>56 marshmallows.

Question: A factory decides to stop making cars and start making motorcycles instead. When it made cars, per month, it cost $100 for materials, they could make 4 cars, and they sold each car for $50. Now that they make motorcycles it costs $250 for materials, but they sell 8 of them for $50 each. How much more profit do they make per month selling motorcycles instead of cars?

They sold $200 worth of cars each month because 4 x 50 = <calculate step="1">4*50</calculate><result step="1">200</result>
They made $100 a month off cars because 200 - 100 = <calculate step="2">200-100</calculate><result step="2">100</result>
They sold $400 worth of motorcycles each month because 8 x 50 = <calculate step="3">8*50</calculate><result step="3">400</result>
They make $150 a month off motorcycles because 400 - 250 = <calculate step="4">400-250</calculate><result step="4">150</result>
They make $50 more a month off motorcycles than cars because 150 - 100 = <<150-100=50>>50

Question: Gwen received a $900 bonus at work and decided to invest this money in the stock market.  She spent one-third of her bonus on stock A, one-third on stock B, and the remaining one-third on stock C.   After one year, stock A and stock B had doubled in value, while stock C had lost half of its value.  At the end of the year, how much were Gwen's stocks worth, in dollars?

One-third of her bonus was $900/3 = $<calculate step="1">900/3</calculate><result step="1">300</result>.
After one year, stock A doubled in value and was worth $300*2 = $<calculate step="2">300*2</calculate><result step="2">600</result>.
After one year, stock B doubled in value and was worth $300*2 = $<calculate step="3">300*2</calculate><result step="3">600</result>.
After one year, stock C had lost half its value and was worth $300/2 = $<calculate step="4">300/2</calculate><result step="4">150</result>.

Question: Jim decides to open up a bike shop.  The most common repair he does is fixing bike tires.  He charges $20 for this and it cost him $5 in parts.  In one month Jim does 300 of these repairs.  He also does 2 more complex repairs for $300 each and cost $50 in parts.  He also sells $2000 profit worth of things from his retail shop.  If rent and other fixed expense for the shop is $4000 a month how much profit did the shop make?

From each tire repair, he made 20-5=$<calculate step="1">20-5</calculate><result step="1">15</result> profit
So repairs made him a profit of 15*300=$<calculate step="2">15*300</calculate><result step="2">4500</result>
The two complex repairs each made him 300-50=$<calculate step="3">300-50</calculate><result step="3">250</result> profit
So those added 250*2=$<calculate step="4">250*2</calculate><result step="4">500</result>
So his total profit from everything was 4500+500+2000=$<<4500+500+2000=7000>>7000
So he made a profit of 7000-4000=$<<7000-4000=3000>>3000

Question: Mary went to the store to buy fruit. Apples cost $1, oranges cost $2, and bananas cost $3. For every 5 fruits that customers buy, the store offers a $1 discount. Mary buys 5 apples, 3 oranges, and 2 bananas. How much will she pay?

For 5 apples, Mary will pay 5*1= <calculate step="1">5*1</calculate><result step="1">5</result> dollars.
For 3 oranges, she will pay 3*2= <calculate step="2">3*2</calculate><result step="2">6</result> dollars.
For 2 bananas, she will pay 2*3 = <calculate step="3">2*3</calculate><result step="3">6</result> dollars.

Question: Mathilda is determined to pay back the money she owes a friend so she decides to pay an initial installment of $125. If she still has 75% left to pay, how much did she owe originally?

Percentage means per 100, so if she still owes 75%, she must have paid 100% - 75% = 25% of the original amount.
25% of the original amount = (25/100)*original amount = $125
Multiplying both sides by (100/25) gives: original amount = (100/25)*$125 = $<calculate step="1">(100/25)*125</calculate><result step="1">500</result>

Question: A school is adding 5 rows of seats to the auditorium. Each row has 8 seats and each seat costs $30. A parent, being a seat manufacturer, offered a 10% discount on each group of 10 seats purchased. How much will the school pay for the new seats?

Ten seats amount to $30 x 10 = $<calculate step="1">30*10</calculate><result step="1">300</result>.
So there is $300 x 10/100 = $<calculate step="2">300*10/100</calculate><result step="2">30</result> discount for each 10 seats purchased.
Thus, the total cost for every 10 seats is $300 - $30 = $<calculate step="3">300-30</calculate><result step="3">270</result>.
The school is going to buy 5 x 8 = <calculate step="4">5*8</calculate><result step="4">40</result> seats.
This means that the school is going to buy 40/10 = <<40/10=4>>4 sets of 10 seats.
Therefore, the school will pay a total of $270 x 4 = $<<270*4=1080>>1080 for the new seats

Question: Janet pays $40/hour for 3 hours per week of clarinet lessons and $28/hour for 5 hours a week of piano lessons. How much more does she spend on piano lessons than clarinet lessons in a year?

First find the total Janet spends on clarinet lessons per week: $40/hour * 3 hours/week = $<calculate step="1">40*3</calculate><result step="1">120</result>/week
Then find the total Janet spends on piano lessons per week: $28/hour * 5 hours/week = $<calculate step="2">28*5</calculate><result step="2">140</result>/week
Then subtract her weekly clarinet spending from her weekly piano spending to find the weekly difference: $140/week - $120/week = $<calculate step="3">140-120</calculate><result step="3">20</result>/week
Then multiply the weekly difference by the number of weeks in a year to find the annual difference: $20/week * 52 weeks/year = $<calculate step="4">20*52</calculate><result step="4">1040</result>/year
