The pie chart shows that shirts made up 11% of the sales made by the sporting goods store.

The number of sales that were shirts = 11% of the total sales

Total sales made by the store is given as 4,560

Number of sales that were shirts = 11/100 × 4,560

= 0.11 × 4,560

= 501.6

Number of sales made that were shirts is approximately 502.
