Answer 1

A

given c = 4t - 160

To obtain the inverse function rearrange making t the subject

Add 160 to both sides

4t = c + 160 ( divide both sides by 4 )

t =
`(c+160)/(4)`, hence

T(c) =
`(c+160)/(4)` → A

Answer 2

The correct answer is A. T(c) = (c + 160)/4

Explanation:

To solve this, we need to start by using c as a standard term instead of in terms of t. Then we simply solve for t.

C = 4t - 160 ----> Add 160

C + 160 = 4t ----> Divide by 4

(C + 160)/4 = t
