Answer: Camp has 3 * 40 boys = 120 girls. Camp Cedar has a total of 40 boys + 120 girls = 160 children. Camp needs 1 counselor per 8 children, so 160 children / 8 children = 20 counselors needed. The answer is 20.
[Question]Anahi bought a 500 pages book to write some notes on. In the first week, she wrote on 150 pages. In the second week, she wrote on 30% of the remaining pages. While continuing writing, she accidentally spilled coffee on the book and damaged 20 percent of the empty pages she was to write on. Calculate the total number of empty pages available for her to write on now.
[Answer]If she bought a 500 pages book and wrote on 150 pages, the number of empty pages remaining is 500 - 150 = 350 pages. She then wrote on 30% of the remaining empty pages on the second week, a total of 30 / 100 * 350 = 105 pages. The number of remaining empty pages is 350 - 105 = 245 pages. When she spilled coffee on the remaining empty pages, the number of damaged pages was 20 / 100 * 245 = 49. The number of empty pages remaining that she could write on is 245 - 49 = 196 pages. The answer is 196.
Q: Julie started her own landscaping business. She charges $4 an hour for mowing lawns and $8 for pulling weeds. In September she mowed lawns for 25 hours and pulled weeds for 3 hours. If she worked the same number of hours in October, how much money did she earn in September and October?
A: She mowed lawns for 25 hours in September, so earned 25 * $4 = $100. She pulled weeds for 3 hours in September, so earned 3 * $8 = $24. She earned $100 + $24 = $124 in September. Finally, for two months working the same hours she earned $124 * 2 = $248. The answer is 248.
Question: The grocery store sells chips for $2 per packet and corn chips for $1.5 per packet. John would like to buy 15 packets of chips, and with the rest of the money he has left, buy as many packets of corn chips as he can. How many packets of corn chips could John buy if he has $45 for his entire purchase?
Answer:
John wants to buy 15 packets of chips, which will cost him 15 * 2 = $30. So John would have 45 - 30 = $15 left for the corn chips. John could buy for the rest of the money 15 / 1.5 = 10 packets of corn chips. The answer is 10.
