Question

A rental car company charges $40 per day to rent a car and $0.06 for every mile driven. Aaden wants to rent a car, knowing that:

He plans to drive 100 miles.
He has at most $130 to spend.

Write and solve an inequality which can be used to determine xx, the number of days Aaden can afford to rent while staying within his budget.

Answer 1

We know that it costs $0.06 for every mile driven and we plan to drive 100 miles, that means we can set the inequality as:

40x + 0.06(100) ≤ 130

40x + 6 ≤ 130

Rearranging the inequality so we have the variable alone on one side, we get:

40x ≤ 124

Divide both sides by 40 to get x alone.

x ≤ 3.1

Solution: Aaden can afford to drive the car for 3 days and stay under his budget.
