Question

5 1 point A hardware store sells bolts for $0.35 apiece. The function (p) = 0.35p relates the total cost of the bolts to the number, p, purchased. What does C (12) mean It cost $12.00 to buy 4.2 bolts It cost $4.20 to buy 12 bolts

Answer 1

You have the following function f(p):

C(p) = 0.35p

which represents the total cost of the bolts to the number p purchased.

Then, for C(12), p=12, and it means that C(12) is the total cost of 12 bolts. To determine what is the cost for p=12, you simply replace this value of p into the function C(p) and makes the operations, just as follow:

C(12) = 0.35(12)

C(12) = 4.2

Hence, 12 bolts will cost $4.2
