On Thursday Walmart sold 210 pounds of ground beef. On Friday they sold twice that amount. On Saturday they only sold 150 pounds. What was the average amount of beef sold per day?
Thoughts? Step-by-step reasoning:
On Friday Walmart sold 2 * 210 pounds = 420 pounds. For all three days Walmart sold 210 + 420 + 150 pounds = 780 pounds. The average amount of beef sold per day is 780 pounds / 3 days = 260 pounds.
Thus, the answer is 260.
