Let's calculate the markup percentage step-by-step based on the given information.

Step 1: Calculate the cost price of the tennis racquets.

The initial cost per racquet is $65.69. The store received two successive discounts:

• A 25% discount for purchasing more than 100 items.
• A 36% discount for purchasing in October.

Apply the first discount of 25%:

$\text{Discounted price after 25\% discount} = 65.69 \times (1 - 0.25) = 65.69 \times 0.75 = 49.2675$

Apply the second discount of 36%:

$\text{Final cost price after 36\% discount} = 49.2675 \times (1 - 0.36) = 49.2675 \times 0.64 = 31.5312$ Thus, the final cost per racquet is $31.53.

Step 2: Calculate the markup.

The selling price of the racquet is $52.96, and the cost price is $31.53. The markup is calculated as: $\text{Markup} = \text{Selling Price} - \text{Cost Price} = 52.96 - 31.53 = 21.43$

Step 3: Calculate the markup as a percent of cost.

The markup percentage is given by: $\text{Markup Percent} = \left(\frac{\text{Markup}}{\text{Cost Price}}\right) \times 100 = \left(\frac{21.43}{31.53}\right) \times 100 \approx 67.96\%$

Final Answer:

The markup as a percent of cost is approximately 67.96%.

Tip: When multiple discounts are applied successively, always apply one at a time and multiply the price by the remaining percentage after each discount.
