Question

Adam can earn money recycling aluminium cans .each can weighs 15g and he can get paid 50p per kg . If Adam earns £15 , how many cans has he recycled?

Answer 1

Our first step in solving this would to calculate the total weight in kilograms for the cans recycled.

Let us assume that "X" is the total weight of cans recycled.

X*0.50 = 15

X = 15/0.5 = 30

Weight of Cans recycled = 30Kg

we know that 1 kg is 1000 grams, so 30 Kg should be = 30*1000 = 30,000 grams

Since each can weighs 15 grams, the total number of cans recycled = 30,000/15 = 2,000 cans

Total number of cans recycled = 2,000 cans
