Write a function rule that gives the total cost c(p) of p pounds of sugar if each pound costs $0.42.

Question

c(p) = p + 0.42

c(p) = 0.42p

c(p) = 42p

Answer 1

To find the total cost \( c(p) \) of \( p \) pounds of sugar, where each pound costs $0.42, the correct function rule is:

\[ c(p) = 0.42p \]

This means the total cost is equal to the price per pound multiplied by the number of pounds.
