[Question]Bert has a garden shop. He buys his products in a warehouse and sells them for $10 more in his shop. From each sale, he has to pay 10% of the value in tax. One day a client came to his shop and bought a barrel for $90. How Much money did Bert make on this sale?
[Answer]First, we need to know how much Bert paid for the barrel in the warehouse, and that is 90 - 10 = $80. The tax from the sale stands at 10 / 100 * 90 = $9. That means Bert earned 90 - 9 - 80 = $1 on the sale. The answer is 1.
Q: Rich likes to take long walks through town. First he walks 20 feet from his house to the sidewalk. Then he walks 200 feet down the sidewalk to the end of the road. Then he makes a left and walks double his total distance so far until he reaches the next intersection. Then he walks half the total distance up to this point again to the end of his route, before turning around and walking the same path all the way back home. How many feet did Rich walk?
A: Rich walks 20 + 200 = 220 feet to get to the end of the road. He then walks double that distance, 220 * 2 = 440 feet to the next intersection. This makes a total of 220 + 440 = 660 feet. He then walks half that distance, 660 / 2 = 330 feet to get to the end of his route. This makes a total of 660 + 330 = 990 feet so far. He then walks that same distance back, for a total of 990 * 2 = 1980 feet in total. The answer is 1980.
Question: A mad scientist created a shrink ray device that, when used on anything, would cause it to shrink by 50%. The scientist, eager to use his new invention, looked through his house for something to shrink zap. The first thing he found and zapped was his wife, who at the time was carrying a tray containing 5 cups filled with coffee. If each coffee cup held 8 ounces of fluid before being zapped, how many ounces of coffee remained after his wife and the cups filled with coffee were shrink zapped?
Answer: Before the zap, the wife held 5 cups, each with 8 ounces of coffee, for a total of 5 * 8 = 40 ounces of coffee. After the zap, the coffee cups and their contents were shrunk by 50%, for a total of 0.5 * 40 = 20 ounces of coffee. The answer is 20.

[Answer]The total cost of the paintbrush, the paints, and the easel was $2.40 + $9.20 + $6.50 = $18.10. Rose needs $18.10 - $7.10 = $11 more. The answer is 11.
