Q: Mrs. Oaklyn buys handmade rugs at $40 each and sells them at $60 each. If she bought 20 rugs, calculate the profit she will make from selling the rugs.
A: Since she buys one rug at $40 and sells it at $60, she makes a profit of $60 - $40 = $20. If she bought 20 rugs at $40 and sold them at $60 each, she made a profit of 20 * $20 = $400. The answer is 400.
Question: Jenna catches an eel that's 1/3 as long as Bill's. If the combined length of their eels is 64 inches, how long is Jenna's eel?
Answer: Let j be the length of Jenna's eel and b be the length of Bill's eel. We know that b = 3j and b + j = 64. Substituting the first equation into the second equation, we get 3j + j = 64. Combining like terms, we get 4j = 64. Dividing both sides by 4, we get j = 16. The answer is 16.
[Question]Dani has 3 cats; Binkie, Frankie and Spaatz. Each cat has a collar decorated with gemstones. Binkie has four times as many gemstones on his collar as does Frankie but Spaatz has two less than half as many gemstones on her collar as does Frankie. If Spaatz has 1 Gemstone on her collar, how many gemstones does Binkie have on his collar?
[Answer]If Spaatz has 2 less than half the number of gemstones as does Frankie, then half as many as Frankie is 1 + 2 = 3 gemstones. If 3 is half the number of gemstones on Frankie's collar, then Frankie has 3 * 2 = 6 gemstones. If Binkie has 4 times as many gemstones as Frankie, then Binkie has 4 * 6 = 24. The answer is 24.
Q: Cindy had 20 marbles which is 5 more than what Lisa had. If Cindy gave her 12 marbles, how many more marbles does Lisa have now?
A: Lisa had 20 - 5 = 15 marbles. Since Cindy gave 12 marbles, then she only has 20 - 12 = 8 marbles left. Since Lisa received 12 marbles, then Lisa has 15 + 12 = 27 marbles now. Hence, Lisa has 27 - 8 = 19 marbles more than Cindy. The answer is 19.
Question: After working out for 3 hours, three friends go out for lunch. Adam spends two-thirds as much money on lunch as Rick. Rick and Jose eat lunch of the same price. If Jose ate lunch worth $45, what is the cost of lunch for all three?
Answer:
Since Rick and Jose's lunch cost was the same, Adam spent 2 / 3 * 45 = $30 on his lunch. The three friends ate food worth 30 + 45 + 45 = $120. The answer is 120.
