you made two deposits to your bank account this month . One deposit was 17.92, and the second deposit was 15.33. Your balance at the end of the month is 72.31, and you made no withdrawals. Which expression shows your balance at the beginning of the month?

a. $72.31+(17.92- 15.33)
b. 72.31-(17.92 - 15.33)
c. 72.31+ 17.92 + 15.33
d. 72.31 - 17.92- 15.33**

yes, of course.

To find the balance at the beginning of the month, we need to subtract the sum of the two deposits from the balance at the end of the month since no withdrawals were made.

The correct expression is:

d. 72.31 - 17.92 - 15.33

This expression represents subtracting the first deposit (17.92) and the second deposit (15.33) from the balance at the end of the month (72.31).
