Question: Peter is raking leaves. It takes him 15 minutes to rake 3 bags of leaves. If he keeps raking at the same rate, how long will it take him to rake 8 bags?
Answer: We are trying to figure out how long it will take Peter to rake 8 bags of leaves, so we'll call that Y. And we know Peter can rake 3 bags of leaves / 15 minutes = 8 bags of leaves / Y. Next, we will multiply to find the cross - products. 3 x Y = 15 x 8 or 3Y = 120. We want to get figure out Y, so we need to get it by itself by dividing by 3, like this: 3Y / 3 = 120 / 3 or Y = 40 minutes. The answer is 40.
[Question]Mike is shopping at the mall. He needs to buy a shirt, a new wallet, and some food for the evening. The shirt costs a third of the value of the wallet. The wallet is $60 more than the cost of the food, on which Mike spent $30. How much did Mike spend that day on the shopping?
[Answer]The wallet costs $60 more than the food, so it's $30 + $60 = $90. So the cost of the shirt is 1 / 3 * $90 = $30. Mike spent that day $30 + $30 + $90 = $150. The answer is 150.
[Question]Two vampires have come to the sleepy village of Willowton, population 300. Every night, each vampire turns 5 more people into vampires. How many vampires are there after two nights?
[Answer]
First find the number of new vampires after one night: 5 people / vampire * 2 vampires = 10 people. Add that to the starting number of vampires to find the total number of vampires after one night: 10 vampires + 2 vampires = 12 vampires. Then find the number of new vampires on the second night: 5 people / vampire * 12 vampires = 60 people. Add that number to the starting number of vampires on the second night to find the total number of vampires after two nights: 60 vampires + 12 vampires = 72 vampires. The answer is 72.
