James decides to try and collect rare artifacts in the field. He spends 6 months researching before going on a 2-year-long expedition for his first find. The second artifact takes 3 times as long for the research and discovery. How long did it take him to find both?
Let's think: The research took 6 / 12 = .5 years. So it took 2 + .5 = 2.5 years for the first artifact. It takes 2.5 * 3 = 7.5 years for the second. So in total it took 2.5 + 7.5 = 10 years to find both.. The answer is: 10.

Mohammad has 80 bags of chips. One quarter of the bags of chips are Doritos. If Mohammad wants to split the bags of Doritos into 4 equal piles, how many bags of Doritos will be in each pile?
Let's think: The number of Dorito bags is 80 / 4 = 20 bags. The number of Dorito bags in each pile is 20 / 4 = 5 bags.. The answer is: 5.

Brian is taping up some boxes. Each box needs three pieces of tape, one as long as the long side and two as long as the short side. If Brian tapes up 5 boxes that measure 15 inches by 30 inches and 2 boxes that measure 40 inches square, how much tape does he need?
Let's think: First find the amount of tape each 15 in x 30 in box needs on the short sides: 2 sides * 15 inches / side = 30 inches. Then add that to the amount of tape each 15 in x 30 in box needs on the long side to find the total amount needed per box: 30 inches + 30 inches = 60 inches. Then multiply that amount by 5 boxes to find the total amount needed: 60 inches / box * 5 boxes = 300 inches. Then find the amount of tape each 40 in x 40 in box needs for its three equal length sides: 3 sides * 40 inches / side = 120 inches. Then multiply that amount by 2 boxes to find the total amount needed: 120 inches / box * 2 boxes = 240 inches. Then add the total amount needed for each box size to find the grand total: 240 inches + 300 inches = 540 inches.. The answer is: 540.

John's cow weighs 400 pounds. It increased its weight to 1.5 times its starting weight. He is able to sell the cow for $3 per pound. How much more is it worth after gaining the weight?
Let's think:
The cow initially weighs 400 * 1.5 = 600 pounds. So it gained 600 - 400 = 200 pounds. So its value increased by 200 * $3 = $600.. The answer is: 600.
