Question: Surfers enjoy going to the Rip Curl Myrtle Beach Surf Festival. There were 1500 surfers at the Festival on the first day, 600 more surfers on the second day than the first day, and 2/5 as many surfers on the third day as the first day. What is the average number of surfers at the Festival for the three days? Think carefully first, then make a decision:
If there were 1500 surfers on the first day, the total for the second day is 1500 surfers + 600 surfers = 2100 surfers. On the third day, the number of surfers was 2 / 5 * 1500 surfers = 600 surfers. The total number of surfers at the Festival in the three days was 1500 surfers + 2100 surfers + 600 surfers = 4200 surfers. The average number of surfers at the Beach Surf Festival for the three days is 4200 surfers / 3 days = 1400 surfers / day. So the answer is 1400.
