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?

Respuesta :

If p=weight of pineapple and q=weight of orange then:

p=7q=q+870.

So 7q=q+870 and 6q=870 making q=145g. Therefore p=7*145=1015g.

p+q=1015+145=1160g.
