Question: Julie, Letitia and Anton decided to have dinner together at a nearby restaurant. Julie orders $10 worth of food, Letitia orders $20 worth of food, and Anton orders $30 worth of food. How much should each pay in tips if they want to split a 20% tip for the whole meal evenly?
Answer: First, we need to determine how much the entire meal costs before we can determine the tip. We perform 10 + 20 + 30 = 60 dollars worth of food. Now we need to find out how much the total tip to be paid is, by multiplying 60 * .2 = 12 dollars in tips. Since they want to split this evenly amongst three people, this works out to 12 / 3 = 4 dollars in tips per person. The answer is 4.
[Question]Every year, four clowns and thirty children go on a carousel. This year, the candy seller, at the carousel, had 700 candies. The candy seller then sold 20 candies, to each of the clowns and the children, who attended. How many candies did he have left?
[Answer]Since there are four clowns at the carousel this year, the candy seller sold 20 * 4 = 80 candies to all the clowns. The thirty children also bought 20 * 30 = 600 candies in total. Altogether, the candy seller sold 600 + 80 = 680 candies to the clowns and children at the carousel. The number of candies the candy seller has left is 700 - 680 = 20. The answer is 20.
Q: The trip from Philip's house to the children's school is 2.5 miles, and the trip to the market is 2 miles. He makes the round trip to school two times (when taking the children to school and when bringing them back) every day for 4 days a week. Then he makes a round trip to the market once during weekends. What is his car's mileage for a typical week?
A: Making the round trip to school means driving from the house to school and then back, for a total of 2.5 + 2.5 = 5 miles. He makes this trip twice in one day for a total of 2 * 5 = 10 miles. He does this 4 times in a week for a total of 4 * 10 = 40 miles. The round trip (once a week) to the market is 2 + 2 = 4 miles. His total mileage for a typical week = 40 + 4 = 44 miles. The answer is 44.
Question: Susie opens a pizza store. She charges $3 per slice and $15 for a whole pizza. If she was able to sell 24 slices of pizza and 3 whole pizzas, how much money did she earn?
Answer:
She was able to earn 24 x 3 = $72 after selling 24 slices. She earned 15 x 3 = $45 after selling 3 whole pizzas. Therefore, she earned a total of $72 + $45 = $117. The answer is 117.
