1 answer

The correct invoice total can be calculated as follows:

First, subtract the customer discount of $5.00 from the subtotal of $42.60:
$42.60 - $5.00 = $37.60

Next, calculate the sales tax of 7.5% on the revised subtotal:
$37.60 * 0.075 = $2.82

Finally, add the sales tax to the revised subtotal to get the correct invoice total:
$37.60 + $2.82 = $40.42

Therefore, the correct invoice total is $40.42.

The answer is B. $40.42.
