Question

Three oranges and two apples cost 3.20

One orange and five apples cost 2.05
find out the unit cost of each fruit

Answer 1

Orange: $0.915

Apple: $0.227

Explanation:

3O + 2A = 3.2

O + 5A = 2.05

O = 2.05 - 5A

3(2.05 - 5A) + 2A = 3.2

6.15 - 15A + 2A = 3.2

2.95 = 13A

A = 0.2269230769

O = 2.05 - 5(0.2269230769)

O = 0.9153846155
