Damon buys lumber worth $562. He gets 20% contractor discount. The sales tax is 6%. his credit card gives him 2% off. How much d
faltersainse [42]

Answer:

<u>$467.05</u>

Step-by-step explanation:

The price is $562

First, 20% off of that:

562 - 20% of 562 = 562 - 0.2(562) = $449.60

Second, he has to pay 6% tax on this amount, so:

6% = 6/100 = 0.06

449.60 + 0.06*449.60 = $476.58

He won't be paying this amount, because paying through credit card will give him 2% discount on this, so:

476.58 - 0.02(476.58) = <u>$467.05</u>

<u></u>

<u>Final Price: $467.05</u>
