Question

An airline offers a discount one-way flight to New York City for $162.80. If the usual price for the ticket is $185.00, what is the percent discount?


12%



10%



15%



25%

Answer 1

You can solve the equation
185 ( 1 - d/100) = 162,80

Answer 2

discount = Usual Price - Amount Paid
discount = 185 - 162.8
discount = $22.2
let Dp = percent discount
\[Dp=\frac{ discount }{ UsualPrice }*100\]
\[Dp=\frac{ 22.2 }{ 185 }*100\]
Dp = 12%
percent discount is 12%
