Question

Alayna is paid £850 per month. Each month she spends 68% of her pay and saves the rest. How many months will it take Alayna to save £4624?​

Answer 1

Answer:

17 months

Step-by-step explanation:

If she spends 68% of her pay, then her saving:

= 100% - 68%

= 32%

total saving = 32% × £850 × n months

£4624 = £272× n

n = £4624 ÷ £272

  = 17 months

Answer 2

100%= percentage of money saved + percentage of money spent
Percentage of money spent = 100% - 68%
=32%

Money saved per month = total salary x percentage of money saved
= 850 x 32% or (32/100)
= 272 £ per month

Money saved = money saved per month x number of months
4624 = 272 x number of months
Number of months = 4624/272
Number of months = 17 months
