Question: Bob is tilling a plot of his garden. The plot is 110 feet wide by 120 feet long. His tiller digs a swath two feet wide, and he can till 1 foot of ground in about 2 seconds. How long will it take him to till this plot of land, in minutes?
Answer: If Bob goes along the side that's 120 feet long, he will till 110 / 2 = 55 rows. Each of these rows are 120 feet long, so he will push the tiller a total of 120 * 55 = 6,600 feet. He tills 1 linear foot of ground every 2 seconds, so it will take him 2 * 6,600 = 13,200 seconds to till this plot. 13,200 seconds is 13,2000 / 60 = 220 minutes. The answer is 220.

Q: Ali has a store that sells fruits and vegetables. He puts 23 kg of kidney apples, 37 kg of golden apples and 14 kg of Canada apples on the shelves. By noon, 36 kg of apples were sold. What is the mass of apples that he has left?
A: You first have to calculate the total mass of apples he had on the shelves, so you add the three kinds of apples: 23 kg + 37 kg + 14 kg = 74kg. Since he sold 36 kg of apples, he still has: 74 kg – 36 kg = 38kg. The answer is 38.
Question: Paul uses 1 can of frosting to frost a layer cake. He uses a half can of frosting for a single cake, or a single pan of brownies, or a dozen cupcakes. For Saturday, he needs to have 3 layer cakes, 6 dozen cupcakes, 12 single cakes and 18 pans of brownies ready and frosted for customer pick up. How many cans of frosting will he need?
Answer: He needs 1 can of frosting per layer cake and he needs to make 3 layer cakes so that's 1 * 3 = 3 cans of frosting. There are 6 dozen cupcakes,12 single cakes and 18 pans of brownies for a total of 6 + 12 + 18 = 36 orders. Each of the 36 orders needs 1 / 2 can of frosting so they need 36 * .5 = 18 cans of frosting. He needs 3 cans of frosting for the layer cakes and 18 cans for the remaining items for a total of 3 + 18 = 21 cans of frosting. The answer is 21.
[Question]Linda is painting her bedroom. Her bedroom has 4 walls, with the room being 20 feet wide by 20 feet long by 8 feet tall. One wall has a 3-foot by 7-foot doorway. A second wall has a 6-foot by 4-foot window. A third wall has a 5-foot by 7-foot doorway to a walk-in-closet. And the fourth wall is completely solid. What is the total area of wall space that Linda will have to paint?
[Answer]The solid wall is 8 ft. * 20 ft. = 160 sq. ft. The doorway is 3 ft. * 7 ft. = 21 sq. ft. The window is 6 ft. * 4 ft. = 24 sq. ft. The closet door is 5 ft. * 7 ft. = 35 sq. ft. The total area of the doors and windows is 21 sq. ft + 24 sq. ft. + 35 sq. ft. = 80 sq. ft. The solid wall is 160 sq. ft., so before the areas of the doors and window are taken into account, the total wall area is 4 * 160 sq. ft. = 640 sq. ft. Taking into account the doors and window, the total wall area Linda will have to paint is 640 sq. ft. - 80 sq. ft. = 560 sq. ft. The answer is 560.
[Question]A shoe company sells $4000 worth of shoes every month. If they want to make $60000 in an entire year how many more dollars per month should they make selling shoes?
[Answer]
The amount of money they currently make in a year is 12 * 4000 = $48000. The additional amount they need to make is $60000 - $48000 = $12000 per year. So, they should make $12000 / 12 = $1000 more every month. The answer is 1000.
