Question: Yoque borrowed money from her sister. She promised to pay it back in 11 months including an additional 10% of the money she borrowed. If she pays $15 per month, how much money did she borrow?
Answer: In 11 months, Yoque will pay a total of $15 x 11 = $165. The amount $165 is 100% + 10% = 110% of the money she borrowed. So, 1% is equal to $165 / 110 = $1.50. Hence, Yoque borrowed $1.50 x 100 = $150. The answer is 150.
[Question]A yearly book sale is held in school where students can sell their old books at a cheaper price. Two-fifths of Lovely's books can be sold for $2.50 each and the rest for $2 each. How much will Lovely earn if all 10 books were sold?
[Answer]Lovely will sell 10 x 2 / 5 = 4 books for $2.50 each. She will sell 10 - 4 = 6 books for $2 each. Her earnings for the 4 books at $2.50 will be $2.50 x 4 = $10. Her earnings for the 6 books for $2 each will be $2 x 6 = $12. Thus, Lovely's total earning if all 10 books are sold is $10 + $12 = $22. The answer is 22.
Q: Tabitha adds 1 serving of honey per cup of tea in the evening. She usually has 2 cups of tea before bed. She buys her honey in a 16-ounce container. If there are 6 servings of honey per ounce, how many nights will she be able to enjoy honey in her tea before bed?
A: She has 1 serving of honey per cup of tea and she has 2 teas at night so she needs a total of 1 * 2 = 2 servings per night. There are 6 servings in 1 ounce and she has a 16 - ounce jar of honey so that's 6 * 16 = 96 servings of honey. Her jar has 96 servings and she has 2 servings a night so 1 jar will last her 96 / 2 = 48 nights. The answer is 48.
Question: Lola plays basketball on her school team. Her team scored twice at many points at their last home game than their first away game. At the second away game, they scored eighteen points more than the previous away game. At the third away game, they scored two more points than at their second. If Lola’s team scored 62 points at their last home game, how many points do they have to score in their next game to bring their cumulative points up to four times the score from their last home game?
Answer: At their following away game, Lola’s team scored half as many points as at their home game, so they scored 62 / 2 = 31 points. At the second away game, they scored 31 + 18 = 49 points. At the third away game, they scored 49 + 2 = 51 points. A cumulative score of four times their last home game is 4 * 62 = 248 points. Thus, Lola’s team has to score 248 - 193 = 55 points to bring their cumulative points up to 248. The answer is 55.
[Question]Samuel is going to the cinema with his brother, Kevin. They both have a total budget of $20 for their outing. Samuel buys his $14 ticket, then spends $6 on drinks and food. Kevin buys his ticket, then spends $2 on drinks. They have both used their entire budget. How much did Kevin spend on food?
[Answer]We know Kevin bought a ticket and drinks, and this cost him 14 + 2 = 16 dollars. Since Kevin spent his entire budget, his food must have cost 20 – 16 = 4 dollars. The answer is 4.
[Question]Billy has four horses. Each one eats 4 pounds of oats, twice a day. How many pounds of oats does he need to feed his horses for 3 days?
[Answer]
At each feeding Billy serves 4 horses x 4 pounds of oats / horse = 16 pounds / feeding. Each day Billy uses 16 pounds of oats / feeding x 2 feedings / day = 32 pounds of oats / day. Triple that amount to find the amount of oats needed to feed the four horses for three days: 32 pounds of oats / day x 3 days = 96 pounds. The answer is 96.
