Question

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

Answer 1

Answer: 2000 cans

Step-by-step explanation:

Let he recycled x cans,

Since the weight of 1 can = 15 gram

⇒ The weight of x cans = 15x gram = 0.015 kg ( 1kg = 100 gram)

Since, The amount he can get for recycling 1 kg of can = 50 penny,

⇒ The amount he get for recycling 0.015 kg of can = 0.015 x×50 =0.75x penny = 0.0075 x pounds ( 1 pounds = 100 penny)

According to the question,

0.0075 x = 15

⇒ 75 x = 150000 = 2000

Thus, he recycled 2000 cans for getting 15 pounds.
