Water is the source of all life, but with the rapid growth of the population, concerns about the overuse of water resources are rising. Water conservation is imminent. In order to prevent residents from wasting water, a certain city stipulates that the standard water usage per household per month is $10m^{3}$. For water usage within the standard, the charge is at the normal rate. If the water usage exceeds the standard, an additional charge is applied for the excess. The table below shows the payment table for Xiao Fang's family for two months in the year $2023$:

| Time/Item | Water Usage ($m^{3}$) | Cost ($/$) |
|-----------|-----------------------|------------|
| January   | 15                    | 35         |
| February  | 18                    | 44         |

Find the normal charging standard and the price for the excess water in this city.
