Answer this question:Mitch is baking a cake and needs 3 cups of flour and two cups of sugar. He doesn't have a one cup scoop, only a 1/3 cup scoop. How many total scoops will he need?
He needs 9 scoops of flour because 3 / (1 / 3) = 9. He needs 6 scoops of sugar because 2 / (1 / 3) = 6. He needs 15 total scoops because 9 + 6 = 15.
The answer is 15.

Answer this 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?
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.

Answer this question:If there were 200 students who passed an English course three years ago, and each subsequent year until the current one that number increased by 50% of the previous year's number, how many students will pass the course this year?
We begin 3 years ago with 200 students, and moving forward to two years ago we find there were 200 * 1.5 = 300 students who passed. At the end of the subsequent year 50% more students pass than last year's 300, so that means 300 * 1.5 = 450 students pass. At the end of the current year there's another 50% increase over the previous year, meaning we have 450 * 1.5 = 675 students pass.
The answer is 675.

Answer this question:Tina buys a loaf of bread for $50, 2oz of ham for $150, and a cake for $200. What percent of the cost is the ham and bread?
The total cost of buying bread and ham was $50 + $150 = $200. Together with the cake, Tina paid $200 + $200 = $400 for the items. Since the total percentage for all the items is 100%, the cost of ham and bread is $200 / $400 * 100% = 50% of the total cost of items.
The answer is 50.
