Problem

A dress originally priced at $80$ dollars was put on sale for $25\%$ off. If $10\%$ tax was added to the sale price, then the total selling price (in dollars) of the dress was

$\text{(A)}\ \text{45 dollars} \qquad \text{(B)}\ \text{52 dollars} \qquad \text{(C)}\ \text{54 dollars} \qquad \text{(D)}\ \text{66 dollars} \qquad \text{(E)}\ \text{68 dollars}$

Solution

After the price reduction, the sale price is $80-.25\times 80 = 60$ dollars. The tax makes the final price $60+.1\times 60 = 66$ dollars $\rightarrow \boxed{\text{D}}$.
