Q: Denny is planning to build a modular home. A 400 square foot Kitchen module costs $20000 and a 150 square foot bathroom module costs $12,000. All other modules cost $100 per square foot. If Denny plans to build a 2,000 square foot modular home containing one kitchen and two bathrooms, how much will it cost, in dollars?
A: The kitchen and two bathroom modules will take up 400 + 150 + 150 = 700 sq. ft. of the 2000 sq. ft. of space. Thus, the remaining modular space is 2000 - 700 = 1300 sq. ft. Cost of the kitchens and bathrooms is $20,000 + $12,000 + $12,000 = $44,000. The cost of the other 1300 sq. ft. of space is 1300 * $100 = $130,000. In total, the cost of the complete 2000 sq.ft. modular home with one kitchen and two bathrooms is $44,000 + $130,000 = $174,000. The answer is 174000.
Question: A lot of people have been sick at Gary's workplace, so he's been working a lot of extra shifts to fill in for people. As a result, he's earned some overtime (where every hour after 40 he earns 1.5 times his normal wage.) His paycheck (before taxes are taken out) came out to $696. If Gary normally earns $12 per hour, how many hours did he work that week?
Answer: Gary earned overtime, so he worked at least 40 hours. for which he was paid 40 hours * $12 / hour = $480 at his normal wage. This means that $696 - $480 = $216 was earned at his overtime wage. His overtime wage is 1.5 his normal wage, or $12 * 1.5 = $18 per hour. So Gary worked $216 / $18 per hour = 12 hours' worth of overtime. So in total, Gary worked 40 hours + 12 hours = 52 hours that week. The answer is 52.
[Question]Mary has 300 sheep and Bob has double the number of sheep as Mary plus another 35. How many sheep must Mary buy to have 69 fewer sheep than Bob?
[Answer]Bob has (300 * 2) + 35 = 635 sheep. For Mary to have 69 sheep fewer than Bob she must own 635 – 69 = 566 sheep. As Mary has already 300 sheep she must buy 566 – 300 = 266 sheep. The answer is 266.
Q: Jon decides to take up baseball. He can throw a fastball at 80 miles per hour.  He goes through intense training 4 times for 4 weeks each time and at the end of the last one he can throw a ball 20% faster. How much speed (in mph) did he gain per week, assuming he gained an equal amount of speed (in mph) each week?
A: He threw the ball 80 * .2 = 16 mph faster. He was training for 4 * 4 = 16 weeks. So he gained 16 / 16 = 1 mph per week. The answer is 1.
Question: A man drives 60 mph for 3 hours. How fast would he have to drive over the next 2 hours to get an average speed of 70 mph?
Answer: To have an average speed of 70 mph over 5 hours he needs to travel 70 * 5 = 350 miles. He drove 60 * 3 = 180 miles in the first 3 hours. He needs to travel another 350 - 180 = 170 miles over the next 2 hours. His speed needs to be 170 / 2 = 85 mph. The answer is 85.
Q: Meena bakes 5 dozen cookies for the school’s bake sale. She sells 2 dozen cookies to her biology teacher, Mr. Stone. Her friend Brock buys 7 cookies, and her friend Katy buys twice as many as Brock. How many cookies does Meena have left?
A:
Meena bakes a total of 5 x 12 = 60 cookies. Mr. Stone buys 2 x 12 = 24 cookies. Brock buys 7 cookies, so Katy buys 2 x 7 = 14 cookies. Meena sells a total of 24 + 7 + 14 = 45 cookies. She has 60 - 45 = 15 cookies left. The answer is 15.
