Question

You work as a cashier for a bookstore and earn $6 per hour. You also baby sit and earn $6 per hour. You want to earn at least $60 per week, but would like to work no more than 12 hours per week. Which system of inequalities, along with y ≥ 0 and x ≥ 0, would you use to solve the real-world problem?

Answer 1

For this case we first define varials:
 x: number of hours working as cashier
 y: number of hours working as a baby sit
 We now write the system of equations:
 6x + 6y ≥ 60
 x + y ≤ 12
 Answer:
 to solve the real-world problem the system of inequalities is:
 6x + 6y ≥ 60
 x + y ≤ 12
