the daily cost of renting a car is $25 plus $0.40 per mile traveled. If Paul paid $143.40 for a day's rental how many mile did he travel

Sagot :

Answer:

295 mi

Step-by-step explanation:

we can write this as an equation. the base fee, with no miles traveled is 25. this will be our y intercept, or b in the equation y = mx + b

our slope is .4

for every 1 mile increase for x, our y increases by .4

so:

y = .4x + 25

set this equal to 143.40

143.40 = .4x + 25

x = 295 mi
