A bicycle at Store $\mathrm{P}$ costs $\$ 200$. The regular price of the same bicycle at Store $\mathrm{Q}$ is $15 \%$ more than it is at Store P. The bicycle is on sale at Store Q for $10 \%$ off of the regular price. What is the sale price of the bicycle at Store Q?
(A) $\$ 230.00$
(B) $\$ 201.50$
(C) $\$ 199.00$
(D) $\$ 207.00$
(E) $\$ 210.00$
At Store Q, the bicycle's regular price is $15 \%$ more than the price at Store $\mathrm{P}$, or $15 \%$ more than $\$ 200$.

Since $15 \%$ of 200 is $\frac{15}{100} \times 200=0.15 \times 200=30$, then $15 \%$ more than $\$ 200$ is $\$ 200+\$ 30$ or $\$ 230$. This bicycle is on sale at Store Q for $10 \%$ off of the regular price, $\$ 230$.

Since $10 \%$ of 230 is $\frac{10}{100} \times 230=0.10 \times 230=23$, then $10 \%$ off of $\$ 230$ is $\$ 230-\$ 23$ or $\$ 207$. The sale price of the bicycle at Store $Q$ is $\$ 207$.

ANSWER: (D)
