Question: Kenny wants to make sure he does more jumping jacks every week than he did the week before. He recorded that last week he did 324 total jumping jacks. On Saturday of this week, he looks at his records and sees that on Sunday he did 34. On Monday he did 20. On Tuesday he skipped a day. On Wednesday he did 123. On Thursday he did 64. On Friday he did 23. How many does he have to do on Saturday to make sure he beats last week's number?
Answer: He has already done 264 this week because 34 + 20 + 123 + 64 + 23 = 264. If he does 60 he will have done as many as last week because 324 - 264 = 60. He has to do 61 on Saturday because 60 + 1 = 61. The answer is 61.
[Question]Tim host a show and they film multiple episodes per day. Each episode is 20 minutes long and it takes 50% longer than that to film each episode. Each week they show 5 episodes. How many hours would it take to film 4 weeks of episodes?
[Answer]Each episode takes 20 * .5 = 10 minutes longer to film than it is. So it takes 20 + 10 = 30 minutes. They are filming 5 * 4 = 20 episodes. So it takes 20 * 30 = 600 minutes. This is equivalent to 600 / 60 = 10 hours. The answer is 10.

Question: Bob wants to build a pyramid out of legos with 3 levels where the bottom level has 7 legos per side and each level has one less lego per side than the level below it. How many legos total will he need?
Answer: First find the total number of legos on the bottom layer: 7 legos * 7 legos = 49 legos. Then find the number of legos per side on the next layer: 7 legos - 1 lego = 6 legos. Then find the total number of legos on the second level: 6 legos * 6 legos = 36 legos. Then find the number of legos per side on the top level: 6 legos - 1 lego = 5 legos. Then find the total number of legos on the top level: 5 legos * 5 legos = 25 legos. Then add the number of legos on each level to find the total number of legos: 49 legos + 36 legos + 25 legos = 110 legos. The answer is 110.
[Question]It takes Polly 20 minutes to cook breakfast every day. She spends 5 minutes cooking lunch. She spends 10 minutes cooking dinner 4 days this week. The rest of the days she spends 30 minutes cooking dinner. How many minutes does Polly spend cooking this week?
[Answer]Polly spends 20 * 7 = 140 minutes cooking breakfast. She spends 5 * 7 = 35 minutes cooking lunch. She spends (10 * 4) + (30 * 3) = 130 minutes cooking dinner. Therefore, she spends 140 + 35 + 130 = 305 minutes cooking this week. The answer is 305.
[Question]At the museum, Bethany saw 4 times more still lifes than portraits. If she saw 80 paintings total, how many portraits did she see?
[Answer]
Let s be the number of still lifes Bethany saw and p be the number of portraits. We know that s + p = 80 and s = 4p. Substituting the second equation into the first equation, we get 4p + p = 80. Combining like terms, we get 5p = 80. Dividing both sides by 5, we get p = 16. The answer is 16.
