Which expression could be used to determine the cost of a $50 video game after a 20 percent discount? $50(0.20) $50(1 – $50)(0.20) $50 – 0.80 $50(0.80)
The correct equation is $50(0.80). The discount is 20% or 0.20, so we multiply the original price by 1-(discount), which is 1-0.2, so we multiply by 0.80.
