barxatty [35]

Answer:

7.27% of the salespersons received turkeys

Step-by-step explanation:

Of the 110 salespersons working at the store, only 8 sold over $10,000.

So those earned turkeys.

As a proportion, this is: 8/110 = 0.0727

To find the percentage, we multiply the proportion by 100%. So

0.0727*100% = 7.27%

7.27% of the salespersons received turkeys
