Question

Which expression could be used to determine the cost of a $50 video game after a 20 percent discount?

Answer 1

The expression that could be used to determine the cost of a $50 video game after a 20 percent discount is:

$50(0.80)

$50(0.80) = $40 discounted amount

$50 * 20% = 10 discount value
$50 - 10 = $40 discounted amount

Answer 2

If you would like to know the expression that could be used to determine the cost of a $50 video game after a 20 percent discount, you can do this using the following steps:

$50 - 20% of $50 = $50 - 20% * $50 = $50 - 20/100 * $50 = $50 - 1/5 * $50 = $50 - 0.20 * $50 = $50 * 0.80 = $40

The correct result would be $50(0.80).
