[Question]Mrs. Gable’s third grade class is on a field trip to the beach. For lunch, Mrs. Gable brought 20 lunches for the 20 students in her class. She included a pack of animal crackers in each lunch bag for dessert. Each pack of animal crackers contained 10 animal crackers. If 2 students did not eat their animal crackers, how many animal crackers were eaten in total among Mrs. Gable’s students?
[Answer]Since 2 students did not eat their animal crackers, 20 - 2 = 18 students ate their animal crackers. The students ate a total of 18 * 10 = 180 animal crackers. The answer is 180.
Q: Frank is walking through a corn maze. He has already spent 45 minutes inside. He has done 4 other corn mazes and finished those in 50 minutes on average. How much longer can he spend inside if he wants to ensure that his average doesn't go above 60 minutes per maze?
A: He needs to keep his total time at 300 or below because 5 x 60 = 300. His total time spent in the other mazes is 200 because 4 x 50 = 200. His total time spent in the five mazes thus far is 245 because 200 + 45 = 245. He can spend 55 more minutes on this maze before his average go above 60 because 300 - 245 = 55. The answer is 55.
Question: Aitana and Jayda went to Silverlake Flea market to buy some handmade crafts. Aitana spent 2/5 times more money than Jayda at the market. If Jayda spent $400, calculate the total amount of money they spent together.
Answer: If Jayda spent $400 at the market, Aitana spent 2 / 5 * 400 = $160 more on handmade crafts. Since Aitana spent $160 more than Jayda at the market, she spent $400 + $160 = $560. The total amount of money they spent together is $400 + $560 = $960. The answer is 960.
[Question]Jack wants to send thank you cards to everyone who got him a gift for his wedding. He sent out 200 invitations. 90% of people RSVPed but only 80% of people who RSVPed actually showed up. Then 10 people who showed up didn't get a gift. How many thank you cards does he need?
[Answer]He got 200 * .9 = 180 RSVP. Of those only 180 * .8 = 144 people showed up. So only 144 - 10 = 134 got him gifts and hence need thank you cards. The answer is 134.
Q: James drives 30 mph for half an hour and then twice as long for twice the speed. How far did he drive in total?
A: His first drive was 30 * .5 = 15 miles. The next leg was .5 * 2 = 1 hour. The speed of the trip was 30 * 2 = 60 mph. So he drove 60 * 1 = 60 miles. So in total he drove 60 + 15 = 75 miles. The answer is 75.
Question: Josh gets together with 7 friends. Everyone including him puts 5 dollars into a pot. First place gets 80% of the money. Second and third place split the rest. How much money does third place get?
Answer:
7 + 1 = 8 people threw money into the pot. So the amount of money in the pot is 8 * 5 = $40. First place gets 40 * .8 = $32. So there is 40 - 32 = $8 left in the pot after first place gets his cut. So third place gets 8 / 2 = $4. The answer is 4.
