Q: The owner of a company needs to install a transformer to power his electrical equipment. He operates three units of machinery that require a running current of 40A each. These appliances require at least twice their running current for starting, and the transformer chosen must account for this. What is the minimum current load that his transformer of choice must be able to carry?
A: Three units require a running current of 40A each for a total current load of 3 * 40A = 120A. They require twice 120A for starting which is 2 * 120A = 240A which is the minimum current load that the transformer must be able to carry. The answer is 240.
Question: Dorothy, Julia, and Robert go to the store to buy school supplies. Dorothy buys half as many pens as Julia. Julia buys three times as many pens as Robert. Robert buys 4 pens. If one pen costs $1.50, how much money did the three friends spend in total on pens?
Answer: Julia buys 4 * 3 = 12 pens. Dorothy buys 12 / 2 = 6 pens. The total number of pens purchased is 4 + 12 + 6 = 22 pens. The total cost of the pens is 22 * $1.50 = $33. The answer is 33.
[Question]James needs 200 blueberries to make a pint of blueberry jam and then a quart of blueberry jam to make a blueberry pie. If there are two pints per quart, how many blueberries does James need to pick to make 6 pies?
[Answer]First find the total number of blueberries needed for one pie: 200 blueberries / pint * 2 pints / pie = 400 blueberries / pie. Then multiply that number by the number of pie to find the total number of blueberries James need: 400 blueberries / pie * 6 pies = 2400 blueberries. The answer is 2400.
Q: If there are sixty-five dolphins in the ocean, and three times that number joins in from a river which has its mouth at the ocean, calculate the total number of dolphins in the ocean.
A: When three times the number of dolphins in the ocean joins in from a river, the number of dolphins in the ocean increases by 3 * 65 = 195. The total number of dolphins in the ocean increases to 195 + 65 = 260. The answer is 260.
Question: Elijah drank 8.5 pints of coffee yesterday. Emilio drank 9.5 pints of water yesterday. How many cups of liquid did the two boys drink yesterday?

Q: Mark collects money for the homeless. He visits 20 households a day for 5 days and half of those households give him a pair of 20s. How much did he collect?
A:
He got money from 20 / 2 = 10 households per day. So that means he got money from 10 * 5 = 50 households. Each of those houses gave 20 * 2 = $40. So he raised 40 * 50 = $2000. The answer is 2000.
