[Question]Pat is hunting for sharks to take photos. For every photo he takes he earns $15. He sees a shark about every 10 minutes. His boat fuel costs $50 an hour. If he shark hunts for 5 hours, how much money can he expect to make in profit?
[Answer]He will use $250 in fuel because 5 x 50 = 250. He will be shark hunting for 300 minutes because 5 x 60 = 300. He can expect to see 30 sharks because 300 / 10 = 30. He will make $450 off these photos because 30 x 15 = 450. He will make $200 in profit because 450 - 250 = 200. The answer is 200.
Q: A mosquito sucks 20 drops of blood every time it feeds on someone. If there are 5000 drops per liter and you have to lose 3 liters of blood to die, how many mosquitoes would have to feed on you to kill you?
A: First find the total number of liters a mosquito sucks in one feeding: 20 drops / 5000 drops / liter = .004 L / feeding. Then divide the lethal amount of blood by the amount of blood one mosquito can drain: 3 L / .004 L / feeding = 750 feedings. The answer is 750.
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.
