Suppose the cost $C$ of shipping a combination of a parcel post package weighing $P$ pounds and a flat-rate envelope together is calculated as follows: There is a fixed fee of $12$ cents for the first pound of the parcel and $5$ cents for each additional pound of the parcel, plus an additional fixed cost of $20$ cents for the flat-rate envelope if it is shipped with the package. Determine the expression for the total shipping cost $C$ in terms of $P$ pounds of the package when these two items are shipped together.
A) $C = 5P + 27$
B) $C = 5P + 32$
C) $C = 12P + 20$
D) $C = 5P + 12$
