Question

When at a conference, Mr. Gary rented a car for a fee of $62.50 plus $0.12 per mile he drives. What is the most miles Mr. Gary can drive without spending more than $320

Answer 1

let x be the most miles Mr. Gary can drive without spending more than $320

320 = $62.50 + $0.12*x

x = 2145.8333miles =12875/6

Mr. Gary can drive 2145.8333miles without spending more than $320

Answer 2

2145.83 miles

Explanation:

Equation

y ≤ 62.50 + 0.12x

Definitions

y = the amount of money.

x = the number of miles

Solution

320 ≤ 62.50 + 0.12x Subtract 62.50 from both sides

320 - 62.50 ≤ 62.50 - 62.50 + 0.12x Combine

257.50 ≤ 0.12x Divide both sides by 0.12

257.50/0.12 ≤ 0.12x / 0.12 Do the division

2145.83 miles ≤ x
