Question

A car rental agency advertised renting a car for $ 23.95 per day and $ 0.32 per mile. If Trevor rents this car for 3 ​days, how many whole miles can he drive on a $ 250 ​budget?

Answer 1

Lets m is the number of miles 

23.95(3) + 0.32m = 250
71.85 + 0.32m = 250
0.32m = 250 - 71.85
0.32m = 178.15
m = 178.15  /  0.32
m = 556.71

answer: Trevor can drive 556 whole miles on a $250 budget

Answer 2

Y=mx +b plug that in , so the 23.95 would be the flat fee then you add 0.32 
       250 =23.95+0.32 subtract from both sides then divide the answer is  10 miles
