[Question]Julie wants to give her favorite cousin a $2345 mountain bike for his birthday. So far, she has saved $1500. Since the birthday is still a few weeks away, Julie has time to save even more. She plans on mowing 20 lawns, delivering 600 newspapers, and walking 24 of her neighbors’ dogs. She is paid $20 for each lawn, 40 cents per newspaper, and $15 per dog. After purchasing the bike, how much money will Julie have left?
[Answer]Mowing lawns will earn Julie 20 * 20 = 400 dollars. Her earnings, in dollars, from delivering newspapers will be 600 * 40 / 100 = 240 dollars. After walking 24 of her neighbor’s dogs, she will earn 24 * 15 = 360 dollars. She will therefore earn a total of 400 + 240 + 360 = 1000 dollars. Combining earnings from her job with her savings will give Julie 1000 + 1500 = 2500 dollars. Subtracting the cost of the mountain bike from the total will leave Julie with a balance of 2500 - 2345 = 155 dollars. The answer is 155.
Q: Peggy buys 3 folders, one each in the colors red, green, and blue. She puts ten sheets of paper in each folder, and then, she puts star-shaped stickers on each sheet of paper. In the red folder, each sheet of paper gets 3 stickers. In the green folder, each sheet of paper gets 2 stickers, and in the blue folder, each sheet gets 1 sticker. What is the total number of stickers Peggy uses?
A: For the red folder, 10 sheets of paper get 3 stickers each, for a total of 10 * 3 = 30 stickers. For the green folder, 10 sheets of paper get 2 stickers each, for a total of 10 * 2 = 20 stickers. For the blue folder, 10 sheets of paper get 1 sticker each, for a total of 10 * 1 = 10 stickers. In total, she uses 30 + 20 + 10 = 60 stickers. The answer is 60.
