Question: A camping site recorded a total of 150 campers for the past three weeks. Two weeks ago, there were 40 campers which was 10 more than the number of campers three weeks ago. How many campers were there last week?
Answer: Three weeks ago, there were 40 - 10 = 30 campers. The total number of campers from three to two weeks ago is 30 + 40 = 70. Hence, there were 150 - 70 = 80 campers last week. The answer is 80.
[Question]Violet is trying to figure out whether she should buy a family pass to the aquarium for $120 or pay for tickets separately. If adult tickets cost $35 and children's tickets cost $20, and Violet's family has 1 adult and 6 children, how much will she pay if she buys separate tickets?
[Answer]First find the total cost of the children's tickets: 6 children * $20 / child = $120. Then add the cost of the adult ticket to find the total cost: $120 + $35 = $155. The answer is 155.
Q: Jason is tired of the neighborhood animals raiding his trash. He pepper-sprays some raccoons and 6 times as many squirrels. If he pepper-sprays 84 animals total, how many raccoons does he pepper-spray?
A: Let r be the number of raccoons Jason pepper - sprays and s be the number of squirrels. We know that r + s = 84 and s = 6r. Substituting the second equation into the first equation, we get r + 6r = 84. Combining like terms, we get 7r = 84. Dividing both sides by 7, we get r = 12. The answer is 12.
Question: An entrepreneur is crowdfunding a new business effort. He has three different dollar amount levels of financial backing options and each level is ten times as high as the previous one. He needs to raise $12000 to get his business off the ground. He succeeded after getting two backers at the highest level of financial backing, three at the second level, and ten at the lowest level. How many dollars was the highest level of financial backing?
Answer: Let L represent the lowest level of financial backing. Thus, the second level is 10L and the highest level is 10 * 10L = 100L. The entrepreneur got 2 highest level backers, 3 second level backers, and 10 lowest level backers, so 2 * 100L + 3 * 10L + 10L = 200L + 30L + 10L = 240L = $12000. Therefore, the lowest level of financial backing was L = 12000 / 240 = $50. Thus, the highest level of financial backing was 10 * 10 * 50 = $5000. The answer is 5000.

[Question]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?
