Question

6. Write an inequality to represent the following constraint.Each oil change ( x ) takes 22 minutes and each tire rotation ( y ) takes 18 minutes. There are a total of 5500 minutes available. ______ ≤ _______

Answer 1

Each oil change ( x ) takes 22 minutes which can be represented as 22x.

Each tire rotation ( y ) takes 18 minutes, can be represented as 18y

Now, we have only 5500 minutes available, therefore the sum of both things can not last more than this time.

The inequality represented is:

$22x+18y\leq5500$
