[Question]: Maria found a store that sells handmade sweaters for $30 and a handmade scarf for $20. She wants to buy one for everyone in her family. She will buy 6 sweaters and 6 scarves. If she has saved $500, how much will be left in her savings after buying all these?
[Answer]: Six sweaters amount to $30 x 6 = $180. Six scarfs amount to $20 x 6 = $120. So, Maria will pay a total of $180 + $120 = $300. Thus, she will be left with $500 - $300 = $200 in her savings.
So the answer is 200.

[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?
[Answer]:
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.
