What is the answer psydag

To find the balance at the beginning of the month, we need to subtract the two deposits from the ending balance. Since there were no withdrawals, the balance at the beginning of the month should be the ending balance minus the sum of the two deposits.

Here are the calculations explained:

Ending balance: $72.31
First deposit: $17.92
Second deposit: $15.33

To find the balance at the beginning of the month, we subtract the deposits from the ending balance:

$72.31 - $17.92 - $15.33

Now, we can simplify this expression:

$72.31 - $33.25

Which gives us:

$39.06

So, the expression that shows the balance at the beginning of the month is:

d. $72.31 - $17.92 - $15.33
