[Question]It takes 30 minutes to make pizza dough and another 30 minutes in the oven for the pizza to cook. If one batch of pizza dough can make 3 pizzas but the oven can only fit 2 pizzas at a time, how many hours would it take for Camilla to finish making 12 pizzas?
[Answer]Camilla needs 12 / 3 = 4 batches of pizza dough. 4 batches of pizza would require 30 x 4 = 120 minutes. Camilla needs to bake the pizzas 12 / 2 = 6 times. 6 times in the oven would take 30 x 6 = 180 minutes. Altogether, it would take 120 + 180 = 300 minutes to finish making 12 pizzas. 300 minutes is 300 / 60 = 5 hours. The answer is 5.
Q: A man is trying to maximize the amount of money he saves each month. In particular, he is trying to decide between two different apartments. The first apartment costs $800 per month in rent and will cost an additional $260 per month in utilities. The second apartment costs $900 per month and will cost an additional $200 per month in utilities. The first apartment is slightly further from the man's work, and the man would have to drive 31 miles per day to get to work. The second apartment is closer, and the man would only have to drive 21 miles to get to work. According to the IRS, each mile a person drives has an average cost of 58 cents. If the man must drive to work 20 days each month, what is the difference between the total monthly costs of these two apartments after factoring in utility and driving-related costs (to the nearest whole dollar)?
A: The mileage cost for the first apartment will be 31 * 20 * 0.58 = $359.60. This makes the total monthly cost of the first apartment 359.60 + 800 + 260 = $1419.60. Similarly, the mileage cost for the second apartment will be 21 * 20 * 0.58 = $243.60. Thus, the total monthly cost of the second apartment is 243.60 + 900 + 200 = 1343.60. Therefore, the difference in total monthly costs is 1419.60 - 1343.60 = $76. The answer is 76.
Question: A shady restaurant is charging customers gratuities after taxes without them being aware. If my total bill was $140, the sales tax in my city is 10%, I ordered a NY Striploin for $80, and I ordered a glass of wine for $10, how much did they charge me for gratuities?
Answer: The total bill before taxes or gratuities was $80 for the steak + $10 for the wine = $80 + $10 = $90. If the tax is 10%, then the taxes paid were $90 * 10% = $9. That means that the total bill before gratuities was $90 + $9 = $99. If the final bill was $140, then you were charged $140 - $99 = $41 for gratuities. The answer is 41.
[Question]A company was contracted to construct three buildings, with the second building being two times as tall as the first building. The third building had to be three times as tall as the combined height of the first and second buildings. If the first building was 600 feet, calculate the total height of the three buildings together.
[Answer]The second building is two times as tall as the first building, a total of 600 * 2 = 1200 feet. The total height of the first and the second building is 1200 + 600 = 1800 feet. The third building is three times as tall as the combined height of the first and second buildings, which is 1800 * 3 = 5400 feet. Together, the three buildings have a total height of 5400 + 1800 = 7200 feet. The answer is 7200.
Q: A church has 120 members. 40% are adults. The rest are children. How many children more children are there than adults?
A: There are 48 adults because 120 x .4 = 48. 60% of members are children because 100 - 40 = 60. There are 72 children because 120 x .6 = 72. There are 24 more children than adults because 72 - 48 = 24. The answer is 24.
Question: Yvonne swims 10 laps in 5 minutes. Her younger sister can swim half as many laps as Yvonne in the same time frame. Their brother Joel can swim three times the number of laps as the youngest sister. How many laps can Joel swim?
Answer:
Yvonne swims 10 laps in 5 minutes and her younger sister swims half as many laps in 5 minutes so she swims 10 / 2 = 5 laps in 5 minutes. Joel can swim 3 times the amount of his youngest sister's 5 laps so he can swim 3 * 5 = 15 laps in 5 minutes. The answer is 15.
