Q: Jar A has 28 marbles. Jar B has 12 more marbles than jar A. Jar C has twice as many marbles as jar B. How many marbles are there altogether?
A: Jar B has 28 + 12 = 40 marbles. Jar C has 2 x 40 = 80 marbles. Therefore, there are 28 + 40 + 80 = 148 marbles altogether. The answer is 148.
Question: Toby, the Alaskan Malamute, can pull a sled at a speed of 20 miles per hour if the sled is unloaded, but he pulls the same sled at a speed of 10 miles per hour if the sled is fully loaded. If Toby takes a continuous 4-part journey, first pulling the loaded sled for 180 miles, then pulling the unloaded sled for 120 miles, then pulling the loaded sled 80 miles, and finally, pulling the unloaded sled another 140 miles, how many hours in total will Toby spend pulling the sled?
Answer: Pulling a loaded sled at 10 mph for 180 miles takes 180 / 10 = 18 hours. Pulling an unloaded sled at 20 mph for 120 miles takes 120 / 20 = 6 hours. Pulling a loaded sled at 10 mph for 80 miles takes 80 / 10 = 8 hours. Pulling an unloaded sled at 20 mph for 140 miles takes 140 / 20 = 7 hours. In total, Toby will have pulled the sled for 18 + 6 + 8 + 7 = 39 hours. The answer is 39.
[Question]There are three times as many girls as boys in the Biology class. The Physics class has 200 students. If the Biology class has half as many students as the Physics class, how many boys are in the Biology class?
[Answer]The Biology class has 200 / 2 = 100 students. The boys in the Biology class are 1 / 4 * 100 = 25 students. The answer is 25.
Q: Alberto spent $2457 on a new engine for his car. Samara spent $25 on oil, $467 on tires and $79 on detailing for her car. How many more dollars did Alberto spend on his car?

Question: Marla has to spend 20 minutes driving one way to her son's school, then 70 minutes attending parent-teacher night, then the same amount of time driving home. How many minutes does Marla spend on this errand in total?
Answer: First multiply Marla's one - way driving time by 2 to find her total driving time: 20 minutes * 2 = 40 minutes. Then add Marla's driving time to the time spent attending the conference to find the total time: 70 minutes + 40 minutes = 110 minutes. The answer is 110.
Q: Janet hires six employees. Four of them are warehouse workers who make $15/hour, and the other two are managers who make $20/hour. Janet has to pay 10% of her workers' salaries in FICA taxes. If everyone works 25 days a month and 8 hours a day, how much does Janet owe total for their wages and taxes for one month?
A:
First figure out how many hours each worker works per month by multiplying the number of days they work by the number of hours a day they work: 25 days * 8 hours / day = 200 hours. Then calculate how much one warehouse worker makes per month by multiplying their hourly rate by the number of hours they work: 200 hours * $15 / hour = $3000. Then multiply that number by 4 to find out how much all the warehouse workers make: $3000 / worker * 4 workers = $12,000. Now multiply the hours each manager works (also 200) by their hourly wage to find out how much one manager makes per month: 200 hours * $20 / hour = $4,000. Now multiply one manager's wages by the number of managers (2) to find their total wage amount: $4,000 / manager * 2 managers = $8,000. Now add the wages for the managers and the workers to find the total cost of the wages: $8,000 + $12,000 = $20,000. Now multiply the total wage bill by 10% to find how much the FICA taxes are: $20,000 * .1 = $2,000. Now add the total wage bill to the total tax amount to find the grand total: $2,000 + $20,000 = $22,000. The answer is 22000.
