3) last year kerry’s take home pay was £15 000 she spent 40% of her take home pay on rent. she used the rest of her take home pay for living expenses, clothes and entertainment in the ratio 3 : 1 : 2 how much did kerry spend on entertainment last year?

3,000. You take 15,000 and multiply by .4 to get how much she spent on rent (6,000). They you subtract the rent money from her total pay to get her money that she spent on living expenses, clothes and entertainment in total (9,000). Since she spent her money in six parts (3+2+1), you divide 9,000 by 6 to get 1,500 to get each part. Since for entertainment she has two parts you multiply 1,500 by 2 to get 3,000.
