Question: Kim drives 30 miles to her friend's house. On the way back she has to take a detour that is 20% longer. She spends 30 minutes at her friend's house. She drives at a speed of 44 mph. How long did she spend away from home?
Answer: The trip back was 30 * .2 = 6 miles longer than the trip there. So it was 30 + 6 = 36 miles. So the total drive was 30 + 36 = 66 miles. That means she drove for 66 / 44 = 1.5 hours. She stayed with her friend 30 / 60 = .5 hours. So the total time was 1.5 + .5 = 2 hours. The answer is 2.
[Question]Luke takes fifty more than five times as many grape jelly beans as vanilla jelly beans. If there are 120 vanilla jelly beans, how many jelly beans are there in total?
[Answer]Luke takes 5 * 120 = 600 grape jelly beans, five times the vanilla jelly beans there are?. Luke's total number of grape jelly beans is fifty more than five times the number of vanilla jelly beans, a total of 600 + 50 = 650. In total, there are 650 + 120 = 770 jelly beans. The answer is 770.
Q: Martha gets prize points every time she shops at her local grocery store. She gets 50 points per $10 spent, plus a 250 point bonus if she spends more than $100. Martha buys 3 pounds of beef for $11 each, 8 pounds of fruits and vegetables for $4/pound, 3 jars of spices for $6 each, and other groceries totaling $37. How many points does Martha get?
A: First find the total cost of the beef: $11 / pound * 3 pounds = $33. Then find the total cost of the fruits and vegetables: $4 / pound * 8 pounds = $32. Then find the total cost of the spices: $6 / jar * 3 jars = $18. Now add the cost of all the items to find Martha's total spending: $33 + $32 + $18 + $37 = $120. Now divide 50 points by $10 to find now many points Martha gets per dollar: 50 points / $10 = 5 points / dollar. Now multiply this exchange rate by Martha's total spending to find how many points she gets before the bonus: $120 * 5 points / dollar = 600 points. Finally, add the 250 point bonus Martha gets for spending more than $100: 600 points + 250 points = 850 points. The answer is 850.
Question: Rollo has 3 guinea pigs, the first guinea pig eats 2 cups of food, the second guinea pig eats twice as much as the first one, and the third guinea pig eats 3 cups more than the second one. How many cups of food does Rollo need to feed all his Guinea pigs?
Answer: The second guinea pig eats 2 x 2 = 4 cups of food. The third guinea pig eats 4 + 3 = 7 cups of food. Therefore, Rollo needs a total of 2 + 4 + 7 = 13 cups of food for the guinea pig. The answer is 13.
[Question]A desert has 3/5 fewer palm trees than a nearby forest, which has 5000 palm trees. How many palm trees are there in both the desert and the forest combined?
[Answer]The desert has 3 / 5 fewer palm trees than the forest, and since the forest has 5000 palm trees, the desert has 3 / 5 * 5000 = 3000 fewer palm trees. The total number of palm trees in the desert is 5000 - 3000 = 2000. Together, the desert and the forest have a total of 5000 + 2000 = 7000 palm trees. The answer is 7000.
[Question]A father is building a playset for his son and needs to purchase lumber, nails, and fabric. When he started planning the project, the necessary lumber cost $450, the nails cost $30, and the fabric cost $80. However, recent economic inflation has caused the price of lumber to increase by 20%, the price of nails to increase by 10%, and the price of fabric to increase by 5%. In dollars, how much more money will it cost to complete the project now (after inflation) than it would have when the father began planning?
[Answer]

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

First, the initial, pre - inflation, cost of the project was 450 + 30 + 80 = $560. Then, the price of the lumber increased to 450 * 1.20 = $540. Similarly, the price of the nails increased to 30 * 1.10 = $33. And the price of the fabric increased to 80 * 1.05 = $84. Therefore, the new, post - inflation, cost of the project is 540 + 33 + 84 = $657. Thus, the cost has increased by 657 - 560 = $97. The answer is 97.
