Answer the following question.
Sara is checking out two different stores to buy a computer. The first store offers a device for $950 with a 6% discount. The second sells the same computer for €920 with a 5% discount. What is the difference in price between the two stores?
Step-by-step reasoning process: The amount of discount in the first store 950 x 6 / 100 = $57. So, the device costs 950 - 57 = $893 in the first store. The amount of discount in the second store is 920 x 5 / 100 = $46. So, the device costs 920 - 46 = $874 in the second store. The difference in price is 893 - 874 = $19.
The answer is 19.

Answer the following question.
Oliver wonders how much water his bathtub can hold. So he takes a bucket that holds 120 ounces and starts filling the bathtub. When it reaches the top, he sees that he filled it 14 times. Then he wonders how much bathwater he uses, so he starts taking away buckets until it gets to the level he puts it at. He needs to take away 3 buckets to do this. Finally, he wonders how much water he uses in a week for his baths, which he takes every day. How much water does he use each week?
Step-by-step reasoning process: He uses 11 buckets to fill his bath normally because 14 - 3 = 11. He uses 1, 320 ounces a day for his baths because 11 x 120 = 1,320. He uses 9, 240 ounces a week for his baths because 7 x 1,320 = 9,240.
The answer is 9240.

Answer the following question.
A concert ticket costs $40. Mr. Benson bought 12 tickets and received a 5% discount for every ticket bought that exceeds 10. How much did Mr. Benson pay in all?
Step-by-step reasoning process: Mr. Benson had a 5% discount for each of the 12 - 10 = 2 tickets. So, those two tickets had a $40 x 5 / 100 = $2 discount each. Hence, each ticket cost $40 - $2 = $38 each. Thus, two discounted tickets amount to $38 x 2 = $76. And the other ten tickets amount to $40 x 10 = $400. Hence, Mr. Benson paid a total of $400 + $76 = $476.
The answer is 476.
