[Question]James is building a hall of mirrors. Three of the walls will be completed covered with glass. If two of those walls are 30 feet by 12 feet and the third is 20 feet by 12 feet, how many square feet of glass does he need?
[Answer]First find the area of one of the long walls: 30 feet * 12 feet = 360 square feet. Then double that amount since there are two walls: 360 square feet * 2 = 720 square feet. Then find the area of the short wall: 20 feet * 12 feet = 240 square feet. Then add that area to the area of the two long walls to find the total area: 720 square feet + 240 square feet = 960 square feet. The answer is 960.
Q: Carmela has $7 and each of her four cousins has $2. How much will Carmela have to give to each of her cousins so that she and her cousins will have the same amount of money?
A: Carmela's four cousins have a total of $2 x 4 = $8. The total money they all have is $7 + $8 = $15. There will be 1 (Carmela) + 4 (cousins) = 5 people who will be sharing equally the money. So each of them should get $15 / 5 = $3. Hence, Carmela has to give a total of $7 - $3 = $4 to her 4 cousins. Therefore, each of her cousins will get $4 / 4 = $1. The answer is 1.
Question: Annie went to a liquidation sale and bought 5 televisions that each cost $50. She also purchased 10 figurines. If Annie spent $260 in total, how much did a single figurine cost in dollars?
Answer: Annie spent 5 * $50 = $250 on televisions. She has $260 - $250 = $10 left for the 10 figurines. A single figurine costs $10 / 10 = $1. The answer is 1.
[Question]Kyle makes $3200.00 every month. His monthly bills include $1250 for rent, $150 on utilities, $400 into retirement & savings accounts, $300.00 on groceries/eating out, $200 for insurance and $200 for miscellaneous expenses. If he’s looking at buying a car with a monthly car payment of $350 how much does that leave for gas and maintenance?
[Answer]Kyle’s monthly bills are 1250 + 150 + 400 + 300 + 200 + 200 = $2,500.00. He makes $3200 and his bills are $2500 so that leaves 3200 - 2500 = $700.00. If he buys a car with a monthly car payment of $350 then that leaves 700 - 350 = $350.00 left over for gas and maintenance. The answer is 350.
Q: A four-layer pyramid is being built with each layer having three times as many sandstone blocks as the layer above it. The top layer is a single block. How many sandstone blocks are in the pyramid?
A: There are 1 * 3 = 3 blocks in the second layer. There are 3 * 3 = 9 blocks in the third layer. There are 9 * 3 = 27 blocks in the fourth layer. Thus, there are 1 + 3 + 9 + 27 = 40 sandstone blocks in the pyramid. The answer is 40.
Question: Tom has a job mowing lawns around his neighborhood. Each month he spends $17 on gas and mows 3 lawns, charging $12 per lawn mowed. Last month he also made extra money pulling weeds for $10. How much profit did Tom earn last month?
Answer:
Tom earns 3 lawns * $12 per lawn = $36 per month. Tom earned $36 + $10 = $46 last month. Tom's profit last month was $46 - $17 gas money = $29. The answer is 29.
