Question

Last year, Jora spent

30% of his salary on rent

2/5 of his salary on entertainment

1/4 of his salary on living expenses.

He saved the rest of his salary.

Jora spent £3600 on living expenses.

Work out how much money he saved.

Answer 1

`money\ saved=\$6,480`

Explanation:

Let

x ----> Jora's salary

we know that

Jora spent

1) 30% of his salary on rent

`30\%=30/100=0.30\\rent=0.30x`

2) 1/4 of his salary on living expenses

`1/4=0.25\\living\ expenses=0.25x`

3) He saved the rest of his salary

`rest\ of\ his\ salary=x-(0.30x+0.25x)=0.45x`

`money\ saved=0.45x`

4) Jora spent £3600 on living expenses

`living\ expenses=0.25x`

so

`3,600=0.25x`

Solve for x

`x=\$14,400`

Find out how much money he saved

Remember that

`money\ saved=0.45x`

substitute the value of x

`money\ saved=0.45(14,400)=\$6,480`
