5 football +3 basketball =700

Minus two. It can be calculated that the price of three basketballs is 1000-700=300 yuan.

The price of each basketball is 100 yuan.

Then the price of each football is (1000- 100×6)÷5=80 yuan.

Then 100-80=20 (yuan)

That is, every basketball and every football is 20 yuan short.

Satisfied and adopted
