This is an algebra question about finding x and y.

Question

You can work a total of no more than 20 hours a week at your two jobs. Baby-sitting pays $5 per hour and you cashier job pays $6 per hour. You need to earn at least $90 per week. What is x and y?  This is a high school algebra question.  I believe it is supposed to be with inequalities.

Answer 1

If I interpret your question correctly, let x represent baby-sitting hours and y cashier hours. Then:

x+y <= 20 and 5x+6y >= 90

There is no single answer but instead a range of them. For example:

If x = 0, 15 >= y <= 20

If y = 0, 18 >= x <= 20

Answer 2

x + y ≤ 20

5x + 6y ≥ 90
