Ryan buys a helmet for $20 and a bike that is on sale for $25 off. at the register, the cashier takes an additional 10% off the total purchase. if the initial price of the bike is $260, what is the final amount ryan will pay? $193.50

$231.50

Explanation: Price of helmet = $20 Price of bike = $260

To solve:

$260 - $25 = $235 (Subtract starting price from the first discount)

$235 x 10% = $23.50 (Take the extra discount off the $25 off price)

$235 - $23.50 = $211.50  (Subtract - get final bike price)

$211.50 + $20 = $231.50 (Add final bike price to helmet price)
