Let us assume that total amount of Nathan's allowance = x
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
22.50 =2x
x = 22.50/2
= 11.25
So $11.25 is the total allowance of Nathan.
Then The amount of money deposited by
Nathan in savings account = (7/9) * 11.25
= 78.75/9
= 8.75
So Nathan deposits $8.75 in his savings account.

Answer:
the fifth number is 70
Step-by-step explanation:
mean (average) of first 5 numbers =50 , Then sum of this 5 numbers = 50*5 =250.
The mean of 4 numbers = 45 . Sum 4 numbers = 45*4 = 180
the fifth number is 250-180=70
(180 +70)/5=50 which is the mean
