Question: Melony makes $21 of profit every time she sells 3 shirts and four times as much profit when she sells two pairs of sandals. How much profit will she make if she sells 7 shirts and 3 pairs of sandals?
Answer: Melony makes $21 * 4 = $84 of profit for two pairs of sandals. Melony makes $84 / 2 pairs = $42 of profit per pair of shoes. Melony makes $21 / 3 shirts = $7 of profit per shirt. For seven shirts, Melony will make 7 shirts * $7 = $49 of profit. For three pairs of sandals, Melony will make 3 pairs * $42 / pair = $126 of profit. Melony will make a total of $49 + $126 = $175 of profit. The answer is 175.

Q: Carly had 42 lollipops to share with her friends. Half of the lollipops were cherry, and the rest were equal amounts of watermelon, sour apple, and grape. How many lollipops were grape?
A: Of her 42 lollipops, half were cherry, so 42 lollipops / 2 = 21 were not cherry. Of the 21 that were not cherry, 1 / 3 of them were grape, so 21 lollipops / 3 = 7 grape lollipops. The answer is 7.
Question: Leonard is 4 years younger than Nina who is half as old as Jerome. If the sum of their ages is 36, what is Leonard's age?
Answer: Let x be the age of Nina. So, Leonard's age is x - 4. And Jerome's age is 2x. Since the sum of their ages is 36, then the equation is x + x - 4 + 2x = 36. By combining like terms, the equation becomes 4x = 40. So the value of x which represents the age of Nina is x = 40 / 4 = 10. Therefore, Leonard is 10 - 4 = 6 years old. The answer is 6.
[Question]Jason has three times as many toys as John. If John has 6 more toys than Rachel and Rachel has 1 toy, how many toys does Jason have?

[Question]Laura took six trips to park. On each trip, she spent 2 hours at the park and an additinal 30 minutes walking to and from the park. What percentage of the total time she took for her trips to the park did Laura spend in the park?
[Answer]
During 6 days, Laura would spend 2 * 6 = 12 hours in the park. If it takes 30 minutes (or 0.5 of an hour) walking to and from the park, then for the six trips, it would take her an additional 0.5 * 6 = 3 hours to walk to and from the park. In total, she would spend a total of 12 + 3 = 15 hours on her six trips. So, the fraction of time spent in the park would be 12 / 15 = 0.8. Thus, converting fraction to percentage, Laura spent 0.8 * 100% = 80% of her trip time at the park. The answer is 80.
