Question

At Ivanna's auto shop, it takes her 15 minutes to do an oil change and 24 minutes to do a tire change. Let x be the number of oil changes she does. Let y be the

number of tire changes she does.
Using the values and variables given, write an inequality describing how many oil changes and tire changes Ivanna can do in at most 2 hours (120minutes)

Plzzz help

Answer 1

15x + 24y <= 120

Explanation:

It takes 15 minutes per oil change, 15x

It takes 24 minutes per tire change, 24y

In at most 120 minutes, so it must be less than or equal to the time available.
