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
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
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
