Janice bought five juices for $10 in total and two sandwiches for $6 in total. How much would she need to pay, if she would only buy one sandwich and one juice?
Janice bought five juices for $10, so one juice costs 10 / 5 = $<T>divide(10, 5)=2.0
She also bought two sandwiches for $6, so one sandwich costs 6 / 2 = $<T>divide(6, 2)=3.0
So for one juice and one sandwich, Janice would need to pay 2 + 3 = $<T>add(2, 3)=5
