Question: 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?
Answer: 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]Two friends, Hubert and Ian, are planning to have a pizza party. One box of pizza is worth $14, and a can of soda is worth $1.80. Hubert orders eight boxes of pizza and ten cans of soda. Ian buys ten boxes of pizza and fifteen cans of soda. How much do they spend in all?
[Answer]The number of boxes of pizza is 8 + 10 = 18 boxes. The number of cans of soda is 10 + 15 = 25 cans. The eighteen boxes of pizza cost 18 x $14 = $252. The cost of 25 cans of soda is 25 x $1.80 = $45. Therefore, the total amount they spend is $252 + $45 = $297. The answer is 297.
Q: Diana is twice as old as Grace is today. If Grace turned 3 a year ago, how old is Diana today?

Question: The novelty shop on the Starship Conundrum sells magazines and chocolates. The cost of four chocolate bars is equal to the cost of 8 magazines. If one magazine costs $1, how much does a dozen chocolate bars cost, in dollars?
Answer: If one magazine costs $1, then 8 magazines cost 8 * $1 = $8. Let's define "x" as the cost of one chocolate bar. The cost of four chocolate bars is equal to the cost of 8 magazines and 4 * x = $8. Dividing each side by 4, we get the cost of one chocolate bar x = $2. Therefore, a dozen chocolate bars would cost 12 * $2 = $24. The answer is 24.
Q: Ben bought a lawnmower for his garden. He paid $100 for it. After six months, the value of the mower dropped by about 25%. Over the next year, the value of the mower dropped another 20% in value. How much is Ben's lawnmower worth after this time?
A:
The first value drop of the lawnmower was 25 / 100 * 100 = $25. So the lawnmower was worth 100 - 25 = $75. Over the next year, the value dropped another 20%, which is 20 / 100 * 75 = $15. So after all this time, Ben's lawnmower is worth 75 - 15 = $60. The answer is 60.
