Question

A pineapple is 7 times as heavy as an orange. The pineapple also weighs 870 grams more than the orange. What is the total weight in grams for the pineapple and orange?

Answer 1

P = pineapple

O = orange

Pineapple is 7 times heavier than orange i.e.

P = 7O

Pineapple also weighs 870 grams more than the orange

I.e. P = O + 870

Substitute the equations.

7O = O + 870

7O-O=870

6O = 870

O = 870/6

O=145g

Plug this value back into original equation.

P=7*145

P=1015
