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

The correct answer is:

2000 cans.

Explanation:

It takes 100 p to make 1 £.  This means we can write 50 p as 0.50£.

He earns 15£; since each kg of cans gives him 50 p, or 0.50£, we divide to find out the number of kg of cans:

15/0.5 = 30

He sells 30 kg of cans.  1 kg = 1000 g; this means that 30 kg = 30(1000) = 30000 g.  Each can is 15 g; this means he sold 30000/15 = 2000 g.
