Question: Dakota and Ben order eggs for $3, pancakes for $2, and 2 mugs of cocoa for $2 each. The tax is $1. Later, Ben then decides to order 1 more batch of pancakes and 1 more mug of cocoa as he is still hungry. How much change should they get from $15?
Answer: The cost of the food is $3 + $2 + $2 + $2 = $9. The original total cost, including tax is $9 + $1 = $10. Ben increases the total cost to $10 + $2 + $2 = $14. They should get $15 - $14 = $1 in change. The answer is 1.
[Question]If the normal hours of operation of Jean's business are 4 pm to 10p every day Monday through Friday, and from 6 pm to 10 pm on weekends, how many hours is the business open in a week?
[Answer]First, we find the number of hours per weekday by subtracting the smaller number time from the larger one, finding 10 - 4 = 6 hours per weekday. As there are 5 weekdays, this means the business is open 6 * 5 = 30 hours a week on the weekdays. Then we find out the amount of time the business is open on a weekend day, using the same process as we did with the weekdays, finding Jean's business is open 10 - 6 = 4 hours each weekend day. Since there are two weekend days, this means they are open 4 * 2 = 8 hours on the weekends. We add these two totals together to find that 30 + 8 = 38 hours per week. The answer is 38.
Q: Three planes are going to the same place but each has a different number of passengers. The first plane has 50, the second had 60, and the third has 40. An empty plane can go 600 MPH, but each passenger makes it go 2 MPH slower. What is their average speed?
A: The first plane goes 100 MPH slower than empty because 50 x 2 = 100. The first plane goes 500 MPH because 600 - 100 = 500. The second plane goes 120 MPH slower because 60 x 2 = 120. The second plane goes 480 because 600 - 120 = 480. The third plane goes 80 MPH slower because 40 x 2 = 80. The third plane goes 520 MPH because 600 - 80 = 520. The total speed is 1500 because 500 + 480 + 520 = 1500. Their average speed is 500 because 1500 / 3 = 500. The answer is 500.
Question: The cash price of a refrigerator was $8000. Samantha wanted to buy the refrigerator but pay in installments. If she paid a deposit of $3000 and paid 30 equal monthly installments of $300 each, calculate how much money she would have saved by paying cash.
Answer: When Samantha paid $300 in 30 equal monthly installments, she paid a total of $9000. Since the higher purchase is a deposit plus the total monthly installments, Samatha paid $3000 + $9000 = $12000 for the refrigerator on higher purchase. If she would have bought the refrigerator on the cash prize, Samantha would have paid $12000 - to $8000 = $4000 less. The answer is 4000.
[Question]A store owner repacked his oils into 200 mL bottles. He was able to make 20 bottles. How many liters of oil did the store owner have?
[Answer]Twenty bottles of oil is equal to 200 mL x 20 = 4000 mL. Since 1 liter is equal to 1000 mL, then the store owner had 4000 / 1000 = 4 liters of oil. The answer is 4.
