Alina charges $4 a ride plus $0.75 a mile as a uber driver. if a person only has $20 how far could they go?

Step-by-step explanation:

$ 4 per ride and 0.75 per mile

y = 0.75x + 4with x being # of miles and y being total cost

if a person only had $ 20so sub in 20 for y and solve for x

20 = 0.75x + 4

20 - 4 = 0.75x

16 = 0.75x

16 / 0.75 = x

x = 21.33 (or 21 1/3) miles <
