Savings = 7/9 of his allowance
Excess = $2.50 or 2/9 of his allowance
to get the amount deposited, we need to first get the total allowance.
2.50 ÷ 2/9 ⇒ 2.50 * 9/2 = 22.5/2 = 11.25
Total allowance = 11.25
amount to be deposited: 11.25 * 7/9 = 78.75/9 = 8.75
Allowence=2.50x9 divided by which gives you an answer of 11.25
Hope this helps you!
Amount of money deposited by Nathan into his savings account = 7x/9
Remaining amount that Nathan spent = $2.50
Now we have to get to the equation for solving the question asked.
7x/9 + 2.50 = x
7x + (9 * 2.50) = 9x
7x + 22.50 = 9x
22.50 = 9x - 7x
x = 22.50/2
So $11.25 is the total allowance of Nathan.
Then The amount of money deposited by
Nathan in savings account = (7/9) * 11.25
So Nathan deposits $8.75 in his savings account.
