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 h
e travel
1 answer:
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
