Question: Ali has a store that sells fruits and vegetables. He puts 23 kg of kidney apples, 37 kg of golden apples and 14 kg of Canada apples on the shelves. By noon, 36 kg of apples were sold. What is the mass of apples that he has left?
Answer: You first have to calculate the total mass of apples he had on the shelves, so you add the three kinds of apples: 23 kg + 37 kg + 14 kg = 74kg. Since he sold 36 kg of apples, he still has: 74 kg – 36 kg = 38kg. The answer is 38.
[Question]Robi and Rudy contributed money to start a business that could earn them profit. Robi contributed $4000, and Rudy contributed 1/4 more money than Robi. If they made a profit of 20 percent of the total amount and decided to share the profits equally, calculate the amount of money each got.
[Answer]If Robi contributed $4000, then Rudy contributed 1 / 4 * 4000 = $1000 more. The total amount of money Rudy contributed is $4000 + $1000 = $5000. Together, the contributed a total of $5000 + $4000 = $9000. They made a 20% profit, a total of 20 / 100 * $9000 = $1800. When they decided to share the profit equally, each received $1800 / 2 = $900. The answer is 900.
Q: A candy store sold 20 pounds of fudge for $2.50/pound, 5 dozen chocolate truffles for $1.50 each and 3 dozen chocolate-covered pretzels at $2.00 each. How much money did the candy store make?
A: 20 pounds of fudge at $2.50 / pounds is 20 * 2.50 = $50.00. The 5 dozen truffles were sold in individual units so a dozen is equal to 12 so 5 * 12 = 60. 60 chocolate truffles, at $1.50 each sold for 60 * 1.50 = $90.00. The 3 dozen chocolate pretzels sold in individual units so a dozen is equal to 12 so 3 * 12 = 36. 36 chocolate pretzels sold for $2.00 each sold for 36 * 2 = $72.00. All total, the store made 50 + 90 + 72 = $212.00 from candy sales. The answer is 212.
Question: Charlotte, Lisa, and Patricia have a joint baseball collection. One of their friends is selling a rare baseball card for $100 on his website. Not wanting to miss such a rare opportunity, they have pooled all their money to buy the card. Patricia has $6. Lisa has five times Patricia’s money, but double Charlotte’s. How much more money do they require?
Answer: Since Patricia has 6 dollars, then Lisa has 6 * 5 = 30 dollars. Patricia’s money is double Charlotte’s, meaning that Charlotte has 30 / 2 = 15 dollars. Adding up all the money they have gives a total of 6 + 30 + 15 = 51 dollars. Since the rare card costs 100 dollars, the girls require an additional 100 - 51 = 49 dollars. The answer is 49.

[Question]Trevor needs to go downtown for a restaurant date. An Uber ride downtown costs $3 more than a Lyft ride. A Lyft ride costs $4 more than a taxi ride. The Uber ride costs $22. If Trevor takes a taxi downtown and tips the taxi driver 20% of the original cost of the ride, what is the total cost of the ride downtown?
[Answer]
The cost of the Lyft ride is $22 - $3 = $19. The original cost of the taxi ride is $19 - $4 = $15. Trevor tips the taxi driver $15 * 0.20 = $3. The total cost of the ride downtown is $15 + $3 = $18. The answer is 18.
