Final answer:
To find the selling price, we calculate the two discounts separately and subtract them from the original price. The selling price is $122.17.
Step-by-step explanation:
To calculate the selling price of the tennis racquets, we need to find the total discount applied.
First, we calculate the first discount of 41%. $100 represents this discount. Let's call the original price of the racquets P.
The equation representing the first discount is: P - 0.41P = 100. Solving this equation, we find that P = $169.49.
Next, we calculate the second discount of 28%.
The equation representing the second discount is: P - 0.28P = selling price. Substituting the value of P we found, the selling price is: $169.49 - 0.28 * $169.49 = $122.17.
Therefore, the tennis racquets were sold for $122.17.
