Answer 2

`x+33.25=72.31`

$39.06

Explanation:

IF no withdrawals were made, the total amount at the end of the month will be the money depositted into the account and the original amount before the deposits. Let this original amount be x. We can write the total at the end of the month as:

`x+17.92+15.33=72.31`

`x+33.25=72.31`

We can solve for x:

`x=72.31-33.25`

`x=39.06`

The amount in the beginning of month was $39.06
