Question: Kyle bakes 60 cookies and 32 brownies. Kyle eats 2 cookies and 2 brownies. Kyle's mom eats 1 cookie and 2 brownies. If Kyle sells a cookie for $1 and a brownie for $1.50, how much money will Kyle make if he sells all of his baked goods?
Answer: Kyle and his mom eat a total of 2 + 1 = 3 cookies. Kyle and his mom eat a total of 2 + 2 = 4 brownies. The number of cookies remaining is 60 - 3 = 57 cookies. The number of brownies remaining is 32 - 4 = 28 brownies. From selling his cookies, Kyle makes 57 * $1 = $57. From selling his brownies, Kyle makes 28 * $1.50 = $42. Kyle would make a total of $57 + $42 = $99 if he sold all of his baked goods. The answer is 99.

Question: Kate has to fill 52 balloons for the party. Each balloon holds 5 gallons of air. For the first 10 minutes, she can fill the balloons at a rate of 8 gallons of air per minute. For the next five minutes, she fills them at half that rate. After that, she fills the rest of the balloons at a rate of 2 gallons of air per minute. How many minutes will it take her to fill all of the balloons?
Answer: She needs to fill a total of 52 * 5 = 260 gallons of air. In the first ten minutes, she fills 8 * 10 = 80 gallons of air. For the next five minutes, she fills 8 / 2 * 5 = 20 gallons of air. That leaves her with 260 - 80 - 20 = 160 gallons of air to fill. It will take her 160 / 2 = 80 more minutes to fill the rest of the balloons. The total time to fill all of the balloons is 10 + 5 + 80 = 95 minutes. The answer is 95.

Question: There was some money in the cookie jar. Doris spent $6 from the cookie jar. Martha spent half as much as Doris. If there were $15 left in the cookie jar, how much money, in dollars, was there in the cookie jar at first?

Question: John decides to go back to school to get his PhD. He first takes 1 year of courses to get acclimated back to school life before starting his PhD. After that, he spends 2 years learning the basics of his field. He then starts research, and he spends 75% more time on research than he did learning the basics. He then spends half as long on writing his dissertation as his acclimation period. How long did it take him to do everything?
Answer:
It took him 2 * .75 = 1.5 years longer to do his research than it took to learn the basics. So it took him a total of 2 + 1.5 = 3.5 years to do research. His dissertation took 1 / 2 = .5 years to write. So everything together took 1 + 2 + 3.5 + .5 = 7 years. The answer is 7.
