Question

HELP EMERGENCY A printing company charges $8.95, plus an additional $.15 for each print over 50. Write an equation that can be used to determine the cost, C, to print an order of p, prints

Answer choices:

c (p) =.15 (x+50) +. 8.95
c (p) = 8.95 (x + 50) + 0.15
c (p) =.15 (x- 50) + 8.95
c (p) = 8.95 (x- 50) +0.15

Answer 1

(c) C(p) =.15 (p- 50) + 8.95

Explanation:

You want an equation for the cost of prints that are $0.15 for each print over 50 plus an additional $8.95.

Translating English

The number of prints over 50 will be (p -50). At $0.15 for each of these, their cost will be ...

0.15(p -50)

When the $8.95 charge is added, the total comes to ...

c(p) = 0.15(p -50) +8.95

Additional comment

The problem statement asks for the function to be written C(p). The answer choices use c(p) with the variable x in the equation where p should be. In effect, none of the answer choices is correct.
