Step-by-step reasoning process: The total bill before taxes or gratuities was $80 for the steak + $10 for the wine = $80 + $10 = $90. If the tax is 10%, then the taxes paid were $90 * 10% = $9. That means that the total bill before gratuities was $90 + $9 = $99. If the final bill was $140, then you were charged $140 - $99 = $41 for gratuities.
[Q & A] The question is A shady restaurant is charging customers gratuities after taxes without them being aware. If my total bill was $140, the sales tax in my city is 10%, I ordered a NY Striploin for $80, and I ordered a glass of wine for $10, how much did they charge me for gratuities?
The answer is 41

Step-by-step reasoning process: Let L be the length and W be the width of the rectangle. Hence L = 4 * W. We now use the area to write 80 = L * W. Substitute L by 4 W in the equation above 80 = 4 * W W = 4 W^2. Solve for W and find L. 4 W^2 = 100. W^2 = 25, W = 5 and. L = 4 * 5 = 20 m.
[Q & A] The question is The length of a rectangle is four times its width. If the area is 100 m2. what is the length of the rectangle?
The answer is 20

Step-by-step reasoning process: The number of cars in the back parking lot was 100 * 2 = 200 times more than those in the front parking lot. There were 200 + 100 = 300 cars in the back parking lot. A total of 300 + 100 = 400 cars were present before the play began. The total number of cars that parked in the theater during the play is 700 - 400 = 300 cars.
[Q & A] The question is Lana and her friends go to a theater on the weekend to watch a new play Joan told them was live. When they arrived, Lana saw 100 cars in the front parking lot. She saw two times more vehicles at the back than there were in the front parking lot. If the total number of cars at the end of the play was 700, how many more cars packed into the parking lot during the play?
The answer is 300

Step-by-step reasoning process: There were 15 pounds of rocks in the bucket because 60 / 4 = 15. There were 10 rocks in the bucket because 15 / 1.5 = 10.
