[Answer]Renaldo = 15 km. Ernesto = (1 / 3) * 15 + 7 = 12 km. Total = 15 + 12 = 27 km. Renaldo and Ernesto drove a total of 27 kilometers. The answer is 27.
Q: The price of a math textbook in the school bookshop is $45. If those sold in bookshops outside the school cost 20% less, how much can Peter save by buying from other bookshops rather than the school's if he wants to buy 3 math textbooks?
A: 20% of $45 is (20 / 100) * $45 = $9. The price of the textbook in other bookshops cost $9 less than $45 which is $45 - $9 = $36. Three textbooks from the school bookshop would cost $45 * 3 = $135. Three textbooks from another bookshop would cost $36 * 3 = $108. Peter can save $135 - $108 = $27 by buying from another bookshop. The answer is 27.
Question: Whenever Katie and her family eat donuts, they need some coffee to dunk them in. She notices that for each donut they need 2 ounces of coffee. Every pot of coffee she makes contains 12 ounces and costs $3 to make. If her family finishes 3 dozen donuts, how much do they spend on coffee?
Answer: He family eats 36 donuts because 3 x 12 = 36. They need 72 ounces of coffee for these because 2 x 36 = 72. This is equal to six pots of coffee because 72 / 12 = 6. This will cost $18 to make because 6 x 3 = 18. The answer is 18.
[Question]If Jim has 20 apples, and Jane has 60 apples, and Jerry has 40 apples, how many times can Jim's number of apples fit into the average amount of apples for a person in the group?
[Answer]First, we need to find the average number of apples per person. We start by adding the three totals together, getting 20 + 60 + 40 = 120 apples. To finish finding the average number, we perform 120 / 3 = 40 apples per person. Since Jim has 20 apples, we divide the average of 40 by Jim's total to find 40 / 20 = 2 times that Jim's amount can fit into the average. The answer is 2.
Q: Carrie is making punch. She adds 6 12-oz cans of Mountain Dew, 28 oz of ice, and a 40 oz bottle of fruit juice. How many 10 oz servings of punch does Carrie have?
A: First find the total volume of the Mountain Dew: 6 cans * 12 oz / can = 72 oz. Then find the total volume of the punch: 72 oz + 28 oz + 40 oz = 140 oz. Then divide the total volume by the volume of each serving to find the number of servings: 140 oz / 10 oz / serving = 14 servings. The answer is 14.
Question: Daria just got a new credit card so she could buy some furniture. Daria has $500 saved ready to pay for the furniture she buys, but the rest of the money will have to stay on her credit card statement until the next month, when she can pay it off with interest. She bought a couch for $750, a table for $100 and a lamp for $50. After she pays the initial $500, how much does she still owe before interest?
Answer:
Daria spends $750 + $100 + $50 on furniture = $900 total on furniture. Of that $900 she spent, she can pay $500 now, so $900 - $500 = $400 that Daria still owes. The answer is 400.
