Given the monthly sales for January, February, and March are 100, 120, and 90 respectively, what is the average monthly sales over these three months?

Explanation:
To find the average, add all the monthly sales and divide by how many months are included. 100 + 120 + 90 equals 310. Divide by 3 months to get 310 ÷ 3 = 103.333..., which rounds to 103.33. This is the value shown among the options. The other numbers would come from leaving a month out or misapplying the division or rounding.
