Question: A bicycle shop owner adds 3 bikes to her stock every week. After 1 month, she had sold 18 bikes but still had 45 bikes in stock. How many bikes did she have originally?
Answer: There are approximately 4 weeks in a month. The shop owner added 3 bikes every week for 4 weeks for a total addition of 3 * 4 = 12 bikes. The shop owner now has the original number of bikes + 12 bikes. She sold 18 bikes within the same time frame. She now has a total of 45 bikes which is: the original number of bikes + 12 - 18 = 45 bikes. The original number of bikes = 45 - 12 + 18 = 51 bikes. The answer is 51.
[Question]Jeremy is driving 600 miles to visit his parents. His average speed for this trip is 50 miles per hour. Every two hours of driving, he makes a rest stop for 15 minutes. His car gets 18 miles per gallon of gas, and his gas indicator comes on when he's used 15 gallons, at which point he stops to refill, which takes 10 minutes. How long, in minutes, does he take to get to his parents' house, if he starts out with a full tank of gas?
[Answer]Jeremy is driving 600 miles, at an average speed of 50 miles per hour, so he will be driving for 600 miles / 50 miles per hour = 12 hours * 60 minutes per hour = 720 minutes. He makes a rest stop every 2 hours of driving, at 2, 4, 6, 8 & 10 hours in = 5 rest stops on the trips. Each rest stop takes 15 minutes so he will spend 5 rest stops * 15 minutes per rest stop = 75 minutes on rest stops. His car gets 18 miles to the gallon, and he stops to refill every 15 gallons, so he will stop to refill every 18 miles per gallon * 15 gallons = 270 miles. 600 miles / 270 miles per refuel = 2.22 refuels, so he'll only make 2 refuels during the trip. He will spend 2 refuels * 10 minute per refuel = 20 minutes refueling his car. In total he will take 720 minutes driving + 75 minutes resting + 20 minutes refueling = 815 minutes. The answer is 815.

Question: Bill has 6 times as many nuts as Harry, and Harry has twice as many nuts as Sue. If Sue has 48 nuts, how many do Bill and Harry have combined?
Answer: If Sue has 48 nuts, and Harry has twice as many nuts as Sue, Harry has 2 * 48 = 96 nuts. Bill has 6 times as many nuts as Harry, and since Harry has 96 nuts, Bill has 96 * 6 = 576 nuts. Combined, Bill and Harry have 576 + 96 = 672 nuts. The answer is 672.
Q: Jenny signs up for dinner theater with 5 of her friends. Each person pays $50 for the ticket and $10 for their entrée, and half the people also buy unlimited drink tickets for $30/person. Then the dinner theater is canceled due to COVID, and each person gets a 90% refund. How much money did the group of six friends lose?
A:
First find the cost of the ticket and the entrée for each person: $50 / person + $10 / person = $60 / person. Then multiply that cost by the number of people to find the total cost of entrees and tickets: $60 / person * 6 people = $360. Now find how many people ordered drink tickets: 6 people / 2 = 3 people. Now find the total cost of the drink tickets: 3 people * $30 / person = $90. Now find the total cost of the evening: $90 + $360 = $450. Now multiply this quantity by 90% to find the amount of the refund: $450 * .9 = $405. Now subtract the refund amount from the total cost to find how much money the friends lost: $450 - $405 = $45. The answer is 45.
