Correct. Alright this one. Sorry for asking so many questions!
You made two deposits to your bank account this month. One deposit was $24.61, and the second deposit was $16.49. Your balance at the end of the month is $72.31, and you made no withdrawals. Write and evaluate an expression for your balance at the beginning of the month.
A $72.31 + ($24.61 – $16.49); $80.43
B $72.31 – ($24.61 – $16.49); $64.19
C $72.31 – $24.61 – $16.49; $31.21
D $72.31 + $24.61 + $16.49; $113.41

Anyway , Since there is no withdraw if you subtract the two deposits from the balance at the end of the month, you'll have the beginning balance.
