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? Let's think first. Chain of thought:
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.
Therefore, the answer is 56.
