Which store has the largest average quarterly sales among Prescott, Cottonwood, Mayer, and Chino Valley?

• A. Mayer store
• B. Cottonwood store
• C. Prescott store
• D. Chino Valley store

Answer: (C)

To find the store with the largest average quarterly sales, calculate the average of the four quarterly figures for each store. Add the four numbers for a store and divide by four to get its quarterly average, then compare the four averages. The store with the highest average is the one that, on average, sells more each quarter.

In this case, the Prescott store has the highest average because its four quarterly sales add up to the greatest total among the stores, so the resulting average is higher than the others. The Mayer, Cottonwood, and Chino Valley stores have smaller quarterly totals, leading to lower averages.
