Question

How long will it take me to save £90 if I get £20 a month?

Answer 1

It will take 4 and a half months, but if you get your salary at the end of the month you have to count 5 months. 

90/20 = 4,5

Answer 2

If you don’t spend any of your money it should only take you approximately 5 months.

£20 per month (Times) 5 months = £100 so you’ll just make £10 over your goal
