Joan needed $100 to buy a graphing calculator for her math class. Her neighbor will
pay her $5 per hour to babysit and her father gave her $10 for mowing the lawn.
Which inequality represents the minimum amount of hours she will need to babysit in
order for her to buy her calculator?
5x - 100 2 10
5x + 10 > 100
5x + 10 2 100
10x + 5 = 100
