An invoice has a subtotal of $42.60 for the items, a new customer discount of $5.00 to be applied before taxes, and a sales tax of 7.5%. What is the correct invoice total?

A.
$45.10

B.
$51.17

C.
$40.79

D.
$40.42
First, we need to calculate the subtotal after applying the new customer discount.
Subtotal after discount = Subtotal - Discount
Subtotal after discount = $42.60 - $5.00 = $37.60
Next, we need to calculate the sales tax on the subtotal after discount.
Sales tax = Sales tax rate * Subtotal after discount
Sales tax = 7.5% * $37.60 = $2.82
Finally, we can calculate the invoice total by adding the subtotal after discount and the sales tax.
Invoice total = Subtotal after discount + Sales tax
Invoice total = $37.60 + $2.82 = $40.42
Therefore, the correct invoice total is $40.42.
The correct option is D.
To find the correct invoice total, we need to calculate the discount, the tax, and add them to the subtotal.
1. Calculate the discount:
Subtract the discount amount from the subtotal.
$42.60 - $5.00 = $37.60
2. Calculate the tax:
Multiply the subtotal after the discount by the tax rate as a decimal.
$37.60 * 0.075 = $2.82
3. Add the tax to the subtotal after the discount:
$37.60 + $2.82 = $40.42
Therefore, the correct invoice total is $40.42.
The correct answer is D. $40.42.
To find the correct invoice total, we need to follow a few steps:
1. Start with the subtotal of $42.60 for the items.
2. Apply the new customer discount of $5.00 to the subtotal. Subtract $5.00 from $42.60: $42.60 - $5.00 = $37.60.
3. Calculate the sales tax amount by multiplying the taxable amount (subtotal after discount) by the tax rate. Multiply $37.60 by 0.075 (7.5% written as a decimal): $37.60 * 0.075 = $2.82.
4. Add the sales tax to the discounted subtotal to get the invoice total. Add $37.60 and $2.82: $37.60 + $2.82 = $40.42.
Therefore, the correct invoice total is $40.42, which corresponds to option D.
