Question: Dorothy sells glass frames at half the price that Jemma sells them. Jemma sells the glass frames at 5 dollars each, selling twice as many frames as Dorothy does. If Jemma sold 400 frames, how much did they make together in total from the sale of the glass frames?
Answer: If Jemma sold 400 glasses frames at $5 each, she made 400 * $5 = $2000. Jemma sold twice as many frames as Dorothy, meaning Dorothy sold 400 / 2 = 200 frames. If Dorothy sold her glasses frames at half the price that Jemma sold hers, then it means she sold her glasses frames at $5 / 2 = $2.5 per glasses frame. In total, Dorothy made $2.5 * 200 = $500 from the sale of her glasses frames. Together, they made $2000 + $500 = $2500 from the sale of the glasses frames. The answer is 2500.
[Question]A craftsman makes 16 jars. This is exactly twice the number of clay pots he made. If each jar has 5 marbles and each clay pot has three times as many, how many marbles are there?
[Answer]16 jars are exactly twice the number of clay pots made by the craftsman, meaning there are 16 / 2 = 8 clay pots. If each jar has 5 marbles, the total number of marbles in the jars is 5 * 16 = 80. Each of the clay pots also has 3 * 5 = 15 marbles. The total number of marbles in the 8 clay pots is 15 * 8 = 120. There are a total of 120 + 80 = 200 marbles. The answer is 200.
Q: Troy makes soup. He buys 4 pounds of beef and 6 pounds of vegetables. The vegetables cost $2 per pound and the beef is 3 times that price. How much does everything cost?
A: The vegetables cost 2 * 6 = $12. The beef cost 2 * 3 = $6 per pound. So the beef cost 4 * 6 = $24. So the total cost is 12 + 24 = $36. The answer is 36.
Question: Owen bred 21 turtles, and Johanna has 5 fewer turtles than Owen. After 1 month, Owen has twice as many turtles as before and Johanna loses half of her turtles and donates the rest to Owen. How many turtles did Owen have?
Answer: Johanna had 21 turtles - 5 turtles = 16 turtles. After 1 month, Owen was left with 21 turtles * 2 = 42 turtles. After 1 month, Johanna was left with 16 turtles / 2 = 8 turtles. After Johanna's donation, Owen was left with 42 turtles + 8 turtles = 50 turtles. The answer is 50.
