Problema Solution
A car rents for $13.95 per day, plus 10 cents per mile. You are on a daily budget of $76. What mileages will allow you to stay within the budget?
Answer provided by our tutors
let
x = the mileage we want to find
the price for rent + 10 cents per x miles = daily budget $76
13.95 + 0.1*x = 76
10 cents = $0.1
by solving 13.95 + 0.1*x = 76 we find
x = (76 - 13.95) / 0.1
x = 620.5 miles
Not more then 620.5 miles allows us to stay in the $76 budget.
