Question

When jeremy gets his allowance he agrees to save part of it his savings and expenses are in the ratio of 7:5 if his daily allowance is $3,find how much he saves each day?

Answer 1

He saves $ 1.75 each day from his allowance.

Step-by-step explanation

The ratio of his savings and expenses is 7 : 5

Lets assume, his savings = 7x dollar and his expenses is 5x dollar

Given that, his daily allowance is $3. So....

`7x+5x=3\\ \\ 12x=3\\ \\ x=(3)/(12)= (1)/(4)= 0.25`

So, the amount of his savings each day
`=7x= (7*0.25)dollar= 1.75 dollar`
