Question: For every black & white cookie that Elsa makes, she has to make the batter, bake the cookies for 15 minutes and then allow to cool. She then has to dip the cookies in white icing and allow the icing to harden for 30 minutes. Then she has to re-dip them in chocolate icing and allowed to harden for an additional 30 minutes. If it takes her 2 hours to make the cookies from start to finish, how long does it take to make the dough and cool the cookies before she can start dipping them?
Answer: It takes 15 minutes to bake, 30 minutes for the white icing to harden and 30 minutes for the chocolate icing to harden so it takes 15 + 30 + 30 = 75 minutes. Every hour has 60 minutes and it takes her 2 hours so it takes 60 * 2 = 120 minutes to make the cookies. It takes 120 minutes to make the cookies from start to finish and she spends 75 minutes baking and hardening icing so it takes her 120 - 75 = 45 minutes to make the batter and cool the cookies. The answer is 45.
[Question]Grant decided to sell his baseball gear since he was now playing football. He sold his baseball cards for $25. He got $10 for his baseball bat and agreed to sell his $30 baseball glove at 20% off. He also sold both pair of his baseball cleats for $10 each. How much money did Grant make?
[Answer]The baseball glove was originally $30 and he agreed to take 20% off so 30 * .20 = $6.00 off. If you take the price of the glove and subtract the discount then $30 - $6 = $24.00. He sold 2 pair of shoes for $10 each so 2 * $10 = $20.00. He got $25 for the cards, $10 for the bat, $24.00 for the glove and $20 for the shoes so he made $25 + $10 + $24 + $20 = $79.00. The answer is 79.

Question: Farmer Steven needs to load his truck up with compost. His tractor can scoop up compost at a rate of 75 pounds per minute. Steven's son, Darrel, wants to help. Using a shovel, Darrel can scoop up 10 pounds per minute. How much time, in minutes, would it take for the two working together at the same time to load up 2550 pounds of compost into the truck?
Answer: Working together at the same time, the rate at which the two would be able to load compost would be 75 + 10 = 85 pounds / minute. At 85 pounds / minute, the 2550 pounds could be loaded in 2550 / 85 = 30 minutes. The answer is 30.
[Question]Alice's white water rafting class is composed of 40 students and 10 instructors, including herself. She has 20 life vests on hand. 20% of her students are bringing life vests. How many more life vests will Alice need to get so that entire class has one?
[Answer]20% of her 40 students will bring their own life vest so .20 * 40 = 8 students will bring their life vests. Alice has 20 life vests and 8 students will bring there's so that's 20 + 8 = 28 life vests. There are 40 students and 10 instructors total so that's 40 + 10 = 50 people in the class. If there are 28 life vests and she has 50 people then she needs to find 50 - 28 = 22 more life vests. The answer is 22.
