a car rents for $40 per day plus 21 cents per mile. you are on a daily budget of $82. what mileage will allow you to stay within your budget?

200 miles will allow to stay within the budget

Step-by-step explanation:

∵ The daily budget is 82

∵ The cost per mile is 21/100 = $0.21

∵ The number of miles is x

∴ The equation of the budget is:

∴ 82 = 40 + 0.21 x

∴ 0.21 x = 82 - 40

∴ 0.21 x = 42

∴ x = 42/0.21 = 200

∴ The number of miles = 200 to stay in the daily budget
