Question: Emmalyn decided to paint fences in her neighborhood for twenty cents per meter. If there were 50 fences in the neighborhood that she had to paint and each fence was 500 meters long, calculate the total amount she earned from painting the fences.
Answer: Step-by-step reasoning process: The total length for the fifty fences is 50 * 500 = 25000 meters. If Emmalyn charged twenty cents to paint a meter of a fence, the total income she got from painting the fences is $0.20 * 25000 = $5000.
So the answer is 5000.

Question: James started a food fight in his school's cafeteria, and the school administration is making him work off the cost of all the food he wasted at minimum wage ($8). James has to pay for 20 wasted pounds of meat at $5/pound, 15 wasted pounds of fruits and vegetables at $4/pound, 60 wasted pounds of bread products at $1.50/pound, and 10 hours of time-and-a-half pay for the janitorial staff, who normally make $10/hour. How many hours will James have to work to pay for everything?
Answer: Step-by-step reasoning process: First find the total cost of the wasted meat: $5 / pound * 20 pounds = $100. Then find the total cost of the wasted vegetables: $4 / pound * 15 pounds = $60. Then find the total cost of the wasted bread products: $1.50 / pound * 60 pounds = $90. Then find the time - and - a - half rate for the janitors: $10 / hour * 1.5 = $15 / hour. Then multiply that by the number of hours to find the total janitorial cost: $15 / hour * 10 hours = $150. Then add up all the costs to find the total cost of everything: $100 + $60 + $90 + $150 = $400. Then divide the total James owes by his hourly wage to find how many hours he needs to work: $400 / $8 / hour = 50 hours.
So the answer is 50.

Question: Thirty-six marbles are divided between Mario and Manny in the ratio 4:5. If Manny decided to give 2 marbles to his brother, how many marbles does Manny have now?
Answer: Step-by-step reasoning process: The marbles are divided into 4 + 5 = 9 parts. Each part consists 36 / 9 = 4 marbles. So Manny had 5 parts x 4 = 20 marbles. After giving 2 marbles to his brother, he now has 20 - 2 = 18 marbles left.
So the answer is 18.

Question: Ann is baking cookies. She bakes three dozen oatmeal raisin cookies, two dozen sugar cookies, and four dozen chocolate chip cookies. Ann gives away two dozen oatmeal raisin cookies, 1.5 dozen sugar cookies, and 2.5 dozen chocolate chip cookies. How many total cookies does she keep?
Answer:
Step-by-step reasoning process: Ann had 3 dozen oatmeal cookies - 2 dozen = 1 dozen oatmeal cookies left. Ann had 2 dozen sugar cookies - 1.5 dozen = .5 dozen sugar cookies left. Ann had 4 dozen chocolate chip cookies - 2.5 dozen = 1.5 dozen chocolate chip cookies left. Ann has a total of 1 + .5 + 1.5 dozen cookies = 3 dozen cookies. 3 dozen cookies is 3 * 12 cookies = 36 cookies remaining.
So the answer is 36.
