Question

Evelyn's car costs her $151 per month plus $0.11 per mile. How many miles can Evelyn drive so that her monthly car expenses are no more than $260? Round your answer down, if necessary to ensure that the budget is not exceeded.

Answer 1

Evelyn can drive 990 miles so her monthly car expenses are no more than $260

Explanation:

Set up an equation:

151 + 0.11 ≤ 260

Subtract 151 from both sides.

0.11 ≤ 109

Divide both sides by 0.11.

x ≤ 990.909091

The question said to round your answer down so the budget doesn't exceed, therefore the answer would be 990 miles.
