The cost, before taxes, of the latest CD released by The Magic Squares is $\$ 14.99$. If the sales tax is $15 \%$, how much does it cost to buy this CD, including tax?
(A) $\$ 17.24$
(B) $\$ 15.14$
(C) $\$ 2.25$
(D) $\$ 16.49$
(E) $\$ 16.50$
Solution 1

Since the sales tax is $15 \%$, then the total price for the CD including tax is

$1.15 \times \$ 14.99=\$ 17.2385$ which rounds to $\$ 17.24$.

## Solution 2

Since the sales tax is $15 \%$, then the amount of tax on the CD which costs $\$ 14.99$ is $0.15 \times \$ 14.99=\$ 2.2485$, which rounds to $\$ 2.25$.

Therefore, the total price of the CD including tax is $\$ 14.99+\$ 2.25=\$ 17.24$.
