4. A car rents for $37 per day plus $0.25 per mile. You are on a daily car budget for $95. What mileage will allow you to stay within (less than or equal) your budget

Let m be the mileage.

Write a an algebraic expression for the current situation.

Budget = Rent per day + cost per mile X no of miles travelled

95 = 37 + 0.25 X m

Subtract 37 fro each side

58 = 0.25 m

Divide each side by 0.25

m = 58/0.25 = 232

Mileage is 232.

I hope it helps!

Let m be the mileage.

Write an algebraic expression for the current situation.

Budget ≤ Rent per day + cost per mile *no of miles travelled.

95 ≤ 37 + 0.25 * m

Subtract 37 from each side.

95 - 37 ≤ 0.25 m

58 ≤ 0.25 m

Divide each side by 0.25.

58/0.25 ≤ m

m ≤ 232.

Mileage is less than or equals to 232.
