[Question]Maria wants to paint a picture and needs some tools to do that. She wants to buy a set of brushes for $20 and some canvas for three times more than the brushes. The paint costs Maria $8 per liter, and she needs at least 5 liters. How much money will she earn on the painting if she will be able to sell it for $200?
[Answer]Maria wants to pay 3 * 20 = $60 for the canvas. Maria needs 5 liters of paint, so the cost of it would be 8 * 5 = $40. So in total Maria will earn 200 - 40 - 60 - 20 = $80 if she will be able to sell the painting at the mentioned price. The answer is 80.
Q: Drew is reseeding his lawn with grass seed. One bag of grass seed covers 250 square feet of lawn. His lawn is 22 feet from the house to the curb and 36 feet from side to side. He bought four bags of seed. How many extra square feet could the leftover grass seed cover after Drew reseeds his lawn?
A: Drew's lawn is 22 * 36 = 792 square feet. He bought enough grass seed to cover 250 * 4 = 1000 square feet. Thus, the leftover grass seed can cover 1000 - 792 = 208 square feet. The answer is 208.
Question: A zoo has 16 pandas, paired into mates (in the same zoo). Only 25% of the panda couples get pregnant after mating. If they each have one baby, how many panda babies are born?
Answer: First divide the number of pandas by 2 to find the number of couples: 16 pandas / 2 = 8 panda couples. Then multiply that number by 25% to find the number of babies: 8 panda couples * 25% = 2 panda babies. The answer is 2.

Q: Kimberly went hiking and took a 4-liter bottle full of water with her. The first time she drank from it, she consumed a quarter of the water in the bottle. Later on, she drank 2/3rd of the remaining water. How much water is left in the bottle (in liters)?
A: Her first drink consumed 1 / 4 * 4 = 1 liter of water. Thus there were 4 - 1 = 3 liters of water left in the bottle. Next, she drank 2 / 3 * 3 = 2 liters. Thus, there were 3 - 2 = 1 liters remaining. The answer is 1.
Question: Hayden eats 1 oz of mixed nuts as an evening snack. He buys the bulk bag of mixed nuts that cost $25.00 a bag and holds 40 oz of mixed nuts. There is currently a $5.00 coupon for this item. How much will each serving of nuts cost, in cents, after the coupon is applied?
Answer:
The nuts are $25.00 and he has a $5.00 coupon, so the nuts are on sale for $25 - $5 = $20.00. He eats 1 oz of nuts every evening and the bag has 40 oz of nuts, so it has 40 / 1 = 40 1 oz servings. The nuts cost $20.00 and there are 40 servings per bag, so his snack is $20 / 40 = $0.50 per serving. The answer is 50.
