Question

1.) The cost to print photos is modeled by C(n), where n represents the number of prints.

Answer 1

Hi Bobby, I bet Jeff N. is in your class? Same question, same time -- maybe you two could study together (COVID-19 permitting) for efficiency?

Answer 2

1.)

If 0 ≤ n ≤ 10

new rate: 0.40n + 0.10n = 0.50n

If 10 < n ≤ 50

new rate: 0.30n + 0.10n = 0.40n

If n > 50

there is a discount of 25%, so it will be 0.40 - 25%

new rate: 0.40n - 0.10n = 0.30n

Correct answer:

C.)

2.)

For all x ≤ 4 the function is a parabola with y-intercept = 2

For all x > 4 the function is a line with slope = 2, and y-intercept = 10

The correct graph is D
