Answer 1

Given:

Joe has $173 in the bank.

He puts 7 weeks earning in the banks.

Now joe has $208 in the bank.

To find:

How much money does joe earn each week?

Solution:

Let x be the same amount of money each week for 7 weeks and puts this money in the bank.

Total earning in 7 weeks = 7x

Total amount of money in bank = Initial amount + 7 Weeks earning

`208=173+7x`

`208-173=7x`

`35=7x`

Divide both sides by 7.

`(35)/(7)=x`

`5=x`

Therefore, joe earns $4 each week.
