Question

Write a function rule that gives the total cost c(p) of p pounds of sugar if each pound costs $0.59.

A. c(p) = p + 0.59

B. c(p) = 59p

C. c(p) = p/0.59

D. c(p) = 0.59p

Answer 1

D. c(p) = 0.59p

Explanation:

The total cost, c(p), to purchase sugar is equal to the product of the pound cost equal to $0.59 and the number of pounds of sugar, p. Thus, the answer to this item is C(p)=0.59p

The total cost, c(p), to purchase sugar is equal to the product of the pound cost equal to $0.59 and the number of pounds of sugar, p. Thus, the answer to this item is,

c(p) = ($0.59)p

We multiply the number of pounds of sugar, p, time the cost per pound ,.59, to get the total cost

c(p) = .59*p
