Answer the following question.
Mary wants 144 cupcakes for her party. Mary has already made 36 cherry cupcakes, and 48 berry cupcakes. Mary wants to make an even number of chocolate and vanilla cupcakes for the rest. How much of each should she make?
Step-by-step reasoning process: Mary currently has 36 cherry + 48 berry cupcakes = 84 cupcakes. Mary needs an additional 144 cupcakes – 84 = 60 cupcakes. Mary wants to split that number evenly between chocolate and vanilla, so 60 / 2 = 30 cupcakes of each flavor.
The answer is 30.

Answer the following question.
Leonard is 4 years younger than Nina who is half as old as Jerome. If the sum of their ages is 36, what is Leonard's age?
Step-by-step reasoning process: Let x be the age of Nina. So, Leonard's age is x - 4. And Jerome's age is 2x. Since the sum of their ages is 36, then the equation is x + x - 4 + 2x = 36. By combining like terms, the equation becomes 4x = 40. So the value of x which represents the age of Nina is x = 40 / 4 = 10. Therefore, Leonard is 10 - 4 = 6 years old.
The answer is 6.

Answer the following question.
Kohen has a business selling apples. Once a week, he orders 10 boxes of apples to add to his stock. If each box has 300 apples and he sells 3/4 of his stock in a certain week, what total number of apples is not sold?
Step-by-step reasoning process: In a week, he orders 10 * 300 = 3000 apples. When 3 / 4 of the stock is sold, the total amount of apples sold becomes 3 / 4 * 3000 = 2250 apples. The amount of apples remaining is 3000 - 2250 = 750 apples.
The answer is 750.

Answer the following question.
James paints a 20 ft by 15 ft mural. It takes him 20 minutes to paint 1 square foot and he charges $150 per hour. How much does he charge to paint the mural?
Step-by-step reasoning process: The mural is 20 * 15 = 300 square feet. So it takes him 300 * 20 = 6000 minutes. So he paints it in 6000 / 60 = 100 hours. That means he charges 100 * 150 = $15000.
The answer is 15000.
