Penny drives a truck. The function p = 20h + 75 represents her daily pay, in dollars, for working h hours. She travels 60 miles each hour. She also receives $0.10 for each bonus mile she drives. The function b = 60h * (0.10) represents the amount she earns for her bonus. Which function represents Penny's earnings, P, for driving h hours?

Penny's earning for driving h hours is represented by the function

P = 26h + 75

Step-by-step explanation:

- The function p = 20h + 75 represents her daily pay

- The function b = 60h * (0.10) represents the amount she earns for her bonus.

Penny's earnings is the addition of her daily pay and bonus.

It is represented by the function P.

P = (20h + 75) + 60h * 0.10

Simplifying this, we have

P = 20h + 75 + 6h

= 26h + 75
