Question

Last year Tom spent 20% of his money on clothes, the rest he spent on food, utilities, socializing and savings in the ratio 2 : 7 : 3 : 4.
If Tom spent £2500 on food, how much did he spend on everything else and how much does he earn in total?

Answer 1

let the amount he spent on food, utilities, socializing and savings be
2x , 7x, 3x, and 4x respectively

2x = 2500

solve for x, then sub back into my definitions
add them all up to get the total expenses.
divide this by .8 to get his total earnings.
