Question

Asif wants to buy a Smart Phone for £360. He has already saved £105.

Each week he is paid £90. He saves 25% of his pay.
How many more weeks must he save for to afford the phone?

Answer 1

12

Explanation:

100%->£90

1%->£90÷100=£0.90

saves->25%->£0.90×25=£22.50

£360-£105=£255

£255÷£22.50=11

11+1=12
