Q: In a class of 300 students, the number of smoking teens is 40% of the class. In a year, 70% of the smoking students are hospitalized from smoking-related complications. Calculate the total number of smoking students from the class who have not been hospitalized from smoking-related complications.
A: If the class has 300 students, there are 40 / 100 * 300 = 120 smoking students. In a year, 70% of the smoking students are hospitalized from smoking - related complications, a total of 70 / 100 * 120 = 84 students. The number of smoking students who've not been hospitalized from smoking - related complications is 120 - 84 = 36. The answer is 36.
Question: A mother is making her own bubble mix out of dish soap and water for her two-year-old son. The recipe she is following calls for 3 tablespoons of soap for every 1 cup of water. If the container she hopes to store the bubble mix in can hold 40 ounces of liquid, and there are 8 ounces in a cup of water, how many tablespoons of soap should she add to the container (assuming that the soap itself doesn't count towards the capacity of the container)?
Answer: The 40 - ounce container can hold 40 / 8 = 5 cups of water. This means that 5 * 3 = 15 tablespoons of soap should be used, since each cup of water requires 3 tablespoons of soap. The answer is 15.
[Question]On Thursday Walmart sold 210 pounds of ground beef. On Friday they sold twice that amount. On Saturday they only sold 150 pounds. What was the average amount of beef sold per day?
[Answer]On Friday Walmart sold 2 * 210 pounds = 420 pounds. For all three days Walmart sold 210 + 420 + 150 pounds = 780 pounds. The average amount of beef sold per day is 780 pounds / 3 days = 260 pounds. The answer is 260.
Q: Grace started her own landscaping business. She charges $6 an hour for mowing lawns, $11 for pulling weeds and $9 for putting down mulch. In September she mowed lawns for 63 hours, pulled weeds for 9 hours and put down mulch for 10 hours. How much money did she earn in September?
A: Grace mowed lawns for 63 hours at $6 / hour, so earned 63 * 6 = $378. Grace pulled weeds for 9 hours at $11 / hour, so earned 9 * 11 = $99. Grace put down mulch for 10 hours at $9 / hour, so earned 10 * 9 = $90. During September Grace earned $378 + $99 + $90 = $567. The answer is 567.

Q: Rick held a fundraiser and is figuring out who still owes money. He marked on a sheet how much everyone has promised to contribute, but he forgot to note how much some people had actually paid. Altogether, everyone has promised to contribute $400, and Rick has actually received $285. Sally, Amy, Derek, and Carl all still owe money. Sally and Carl both owe equal amounts, Amy owes $30, and Derek owes half as much as Amy. How much, in dollars, do Sally and Carl each owe?
A:
In total, Rick is still owed 400 - 285 = $115. Derek owes half as much as Amy, so he owes $30 / 2 = $15. This means that Sally and Carl owe a combined total of $115 - $30 – $15 = $70. As they owe equal amounts, they therefore owe $70 / 2 = $35 each. The answer is 35.
