5. Cate earns $20 per hour at her job. She pays $1.50 in bus fare each way. How many hours must she work to end up with $117?

Cate earns $20 per hour, so we are looking for the number of hours: 20x

Cate pays $1.50 for the bus each way, implying that she rides the bus twice in a day: 3

Cate must end up with $117: 117

117 = 20x + 3

114 = 20x

x = 5.7 hours

Cate must work 5.7 hours to end up with $117.

Hope this helps!! :)
