[Question]Jim reads at a rate of 40 pages an hour. He reads a total of 600 pages per week. He increases his reading speed to 150% of its former speed but reads 4 hours less per week. How many pages does he read a week now?
[Answer]He read 600 / 40 = 15 hours per week. So now he reads 15 - 4 = 11 hours per week. She now reads 40 * 1.5 = 60 pages per hour. So she reads 11 * 60 = 660 pages per week. The answer is 660.
Q: Jenny got a 95 on her paper. Jason's grade was 25 points less than Jenny's, and Bob's grade was equal to half of Jason's grade. What was Bob's grade?
A: First find Jason's grade by subtracting 25 from Jenny's grade: 95 - 25 = 70. Then divide Jason's grade by 2 to find Bob's grade: 70 / 2 = 35. The answer is 35.
Question: Andy gets a cavity for every 4 candy canes he eats. He gets 2 candy canes from his parents and 3 candy canes each from 4 teachers. Then he uses his allowance to buy 1/7 as many candy canes as he was given. How many cavities does he get from eating all his candy canes?
Answer: First find how many candy canes Andy gets from his teachers: 3 canes / teacher * 4 teachers = 12 canes. Then add the number of candy canes he gets from his parents: 12 canes + 2 canes = 14 canes. Then divide that number by 7 to find the number of canes he buys: 14 canes / 7 = 2 canes. Then add the number of candy canes he gets from each source to find the total number: 2 canes + 14 canes = 16 canes. Then divide the total number of candy canes by the number of candy canes it takes to get one cavity to find the number of cavities Andy gets: 16 canes / 4 canes / cavity = 4 cavities. The answer is 16.

[Answer]Tory sold 12 packs + 7 packs = 19 packs to his family members. Tory sold 19 packs + 5 packs = 24 packs in total. He has to sell 50 packs - 24 packs = 26 more packs of cookies to reach his target. The answer is 26.
Q: Manny is making lasagna for dinner with his four friends, Lisa, Raphael, Aaron, and Kai. He needs to know how many pieces to cut the lasagna into to serve it. Manny only wants one piece. Aaron doesn't like lasagna much and will probably only eat garlic bread and salad. Kai is always hungry and will eat twice as much as Manny. Raphael always eats half the amount Manny does, but his sister Lisa loves lasagna and will eat two pieces, plus any Raphael has left of his piece. How many pieces should Manny cut his lasagna into?
A: Manny will eat 1 piece. Aaron will eat 0 pieces. Kai will eat twice as much as Manny, so he will eat 2 * 1 = 2 pieces. Raphael will eat half as much as Manny, so he will eat 1 * 1 / 2 = 1 / 2 piece. Lisa will eat 2 pieces plus the remainder of Raphael's piece, so she will eat 2 + 1 / 2 = 2 1 / 2 pieces. Together, they will eat 1 + 0 + 2 + 1 / 2 + 2 1 / 2 = 1 + 2 + 3 = 6 pieces. Thus, Manny should cut his lasagna into 6 pieces. The answer is 6.
Question: Madeline wants to plant 20 flowers in her garden. She assumes that about half of the seeds she plants will die before they bloom. However, the flower shop only sells packs of seeds with 25 seeds per pack. Each pack is $5. How much will Madeline spend on seeds to plant 20 flowers?
Answer:
Madeline needs to buy 2 * 20 = 40 seeds to make sure that she will have 20 flowers. Thus, Madeline will need to buy 2 packs of flowers to have at least 40 seeds. Thus, Madeline will spend 2 * 5 = $10 on seeds. The answer is 10.
