Question

A grocery delivery service charges $0.80 per mile and a set fee of $5.40. Which function models this situation? A. Y = 0.8x + 5.4 B. Y = –0.8x + 5.4 C. Y = 5.4x + 0.8 D. Y = 5.4x – 0.8

Answer 1

A

Explanation:

Answer 2

A. y = 0.8x + 5.4

Explanation:

Make each mile be represented by the variable x, therefore the $0.80 per mile will be represented by 0.8x. The set fee is always going to be there for each time you order, so you will just add 5.40 to 0.8x.

The function is y = 0.8x + 5.4.
