Records for Sale

The Puzzler

RAY: Here's the answer. During the record sale in Week #1, the records in the pile marked 2 for $1 were priced at 50 cents each. And the records in the pile marked 3 for $1 were priced at 33.33 cents each.

During in Week #2, the records were all marked 5 for $2, which averages out to 40 cents per record. And that average price is the problem. Because if you averaged the price of the records for sale in Week #1, the true average is 41.67 cents.

To make $25 in the record sales in Week #2, the clerk should have priced the records at 5 for $2.08 to reach a total sales figure of $25.
