Answer:
[tex]money\ saved=\$6,480[/tex]
Step-by-step explanation:
Let
x ----> Jora's salary
we know that
Jora spent
1) 30% of his salary on rent
[tex]30\%=30/100=0.30\\rent=0.30x[/tex]
2) 1/4 of his salary on living expenses
[tex]1/4=0.25\\living\ expenses=0.25x[/tex]
3) He saved the rest of his salary
[tex]rest\ of\ his\ salary=x-(0.30x+0.25x)=0.45x[/tex]
[tex]money\ saved=0.45x[/tex]
4) Jora spent £3600 on living expenses
[tex]living\ expenses=0.25x[/tex]
so
[tex]3,600=0.25x[/tex]
Solve for x
[tex]x=\$14,400[/tex]
Find out how much money he saved
Remember that
[tex]money\ saved=0.45x[/tex]
substitute the value of x
[tex]money\ saved=0.45(14,400)=\$6,480[/tex]
