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?

First subtract the $25 sale discount from the bike’s initial price: $260 − $25 = $235. Add the $20 helmet to get a $255 purchase total. The cashier takes 10% off that total, so Ryan pays 90% of $255: $255 × 0.90 = $229.50. The correct choice is D, $229.50.
