Q: Jennifer wants to go to a museum. There is one 5 miles away from her home and one 15 miles away. If Jennifer goes to both museums on two separate days, how many miles total will she travel?
A: Jennifer's home is 5 miles away from the first museum, so the round trip back and forth is 5 miles there + 5 miles back = 10 miles altogether. On another day Jennifer goes to a museum 15 miles away + 15 miles to return home = 30 miles total. Combined, Jennifer travels 10 miles on the first day + 30 miles on the second day = 40 miles Jennifer travels total. The answer is 40.
Question: Mr. Smith has incurred a 2% finance charge because he was not able to pay on time for his balance worth $150. If he plans to settle his balance today, how much will Mr. Smith pay?

[Question]A singer is planning on releasing 3 songs in a month. If he worked on one song for 10 hours a day, and each song took 10 days to be completed, calculate the total number of hours he took to complete the 3 songs.
[Answer]If he worked on a song for 10 hours a day, the total number of hours he takes to complete one song is 10 * 10 = 100 hours. If one song took 100 hours to complete, the total number of hours the three songs took to be completed is 3 * 100 = 300 hours. The answer is 300.
Q: James is trying to avoid eating too much sodium. He's making a recipe that calls for 2 teaspoons of salt and 8 oz of parmesan cheese. Salt has 50 mg of sodium per teaspoon and parmesan has 25 mg of sodium per oz. If he can't reduce the salt, how many fewer ounces of parmesan cheese does he need to use to reduce the total amount of sodium by 1/3rd?
A: First find how much sodium the parmesan has in total by multiply the amount of sodium per ounce by the number of oz: 25 mg / oz * 8 oz = 200 mg. Then use the same process to find how much sodium is in the salt: 50 mg / tsp * 2 tsp = 100 mg. Then find the total sodium in the recipe by adding the sodium from the cheese and the salt: 100 mg + 200 mg = 300 mg. Then multiply the total amount of sodium by 1 / 3 to find how much less sodium James wants: 300 mg * 1 / 3 = 100 mg. Then divide this amount by the amount of sodium per ounce of cheese to find how many fewer ounces of cheese he needs: 100 mg / 25 mg / oz = 4 oz. The answer is 4.
Question: A man owned 1/2 of a lot. He sold 1/10 of his share for the amount of $460. What is the worth of the entire lot?
Answer: If 1 / 10 of the man's lot is equal to $460, then the man's land is worth $460 x 10 = $4600. Since 1 / 2 of the whole lot is worth $4600, then the whole lot is worth $4600 x 2 = $9200. The answer is 9200.
Q: Oscar wants to train for a marathon. He plans to add 2/3 of a mile each week until he reaches a 20-mile run. How many weeks before the marathon should he start training if he has already run 2 miles?
