Jan is making candy necklaces for herself and a few friends. Everyone receives a candy necklace each and each candy necklace is made up of 10 pieces of candies. The pieces of candies come from blocks of candy, which each produce 30 pieces of candy. If Jan breaks down 3 blocks of candy and every single piece of candy from this is used in the candy necklaces, how many friends receive a candy necklace? Give the rationale and then the answer.
Let's think step by step. There are a total of 3 blocks of candy * 30 pieces of candy per candy block = 90 pieces of candy. Using this, Jan can create 90 pieces of candy / 10 pieces of candy per candy necklace = 9 candy necklaces. As Jan is keeping a candy necklace too, there must have been enough candy necklaces for 9 candy necklaces 1 candy necklace for Jan = 8 friends.. The answer is: 8.

Janet buys 45-pound containers of cat litter for $21 each. If her cat litter box holds 15 pounds of cat litter, and she changes out the litter weekly, how much will it cost, in dollars, for her to buy enough litter to last 210 days? Give the rationale and then the answer.
Let's think step by step. If she changes the box weekly, then in 210 days, she will change the box 210 / 7 = 30 times. At 15 pounds of litter for every box change, she will require 30 * 15 = 450 pounds of cat litter in 210 days. If she buys 45 - pound containers, then for 450 pounds she will need to buy 450 / 45 = 10 containers of litter. At $21 per container, to buy enough cat litter for 210 days, it will cost 10 * $21 = $210.. The answer is: 210.

Lucius owns a small business and spends $10 every day on ingredients. He then makes a portion of French Fries and a portion of Poutine and sells them to the market, paying ten percent of his weekly income as tax. If the price of French fries is $12 and the price of Poutine is $8, how much does he earn every week after paying the taxes, selling all his products, and buying all the ingredients? Give the rationale and then the answer.
Let's think step by step. He earns $12 + $8 = $20 after selling the French fries and Poutine every day. So, he earns $20 x 7 = $140 every week. And the total amount he pays for the taxes is $140 x 0.10 = $14. So, his income after paying the weekly taxes is $140 - $14 = $126. Lucius spends $10 x 7 = $70 for the ingredients every week. Therefore, his total income every week after buying all the ingredients and paying the taxes is $126 - $70 = $56.. The answer is: 56.
