During a sale, CDs that normally cost $6.98 each were priced at 2 for $12.50. Pete bought 4 CDs at the sale price. How much money did he save by buying the 4 CDs on sale?

Answer 1

To find out how much Pete saved by buying the CDs on sale, we first need to calculate the normal price of the 4 CDs and then compare it to the sale price.

1. Calculate the normal price for 4 CDs: The normal price of one CD is $6.98. Thus, for 4 CDs, the normal cost would be: \[ \text{Normal price} = 4 \times 6.98 = 27.92 \]

2. Calculate the sale price for 4 CDs: The sale price is 2 CDs for $12.50. Therefore, for 4 CDs (which is 2 pairs), the sale cost is: \[ \text{Sale price} = 2 \times 12.50 = 25.00 \]

3. Calculate the savings: The savings can be calculated by subtracting the sale price from the normal price: \[ \text{Savings} = \text{Normal price} - \text{Sale price} = 27.92 - 25.00 = 2.92 \]

Thus, Pete saved $2.92 by buying the 4 CDs on sale.
