Problem

A refrigerator is offered at sale at $250.00 less successive discounts of 20% and 15%. The sale price of the refrigerator is:

$\textbf{(A) } \text{35\% less than 250.00} \qquad \textbf{(B) } \text{65\% of 250.00} \qquad \textbf{(C) } \text{77\% of 250.00} \qquad \textbf{(D) } \text{68\% of 250.00} \qquad \textbf{(E) } \text{none of these}$

Solution

The first discount takes off $20\%$ of the price, so the cost of the refrigerator is $0.8\cdot250$ . The next discount takes off $15\%$ , so the cost of the refrigerator is now $0.8\cdot0.85\cdot250=0.68\cdot250$ . Thus, the sale price of the refrigerator is $\boxed{\textbf{(D)} \text{68\% of 250.00}}$ .
