Question

You buy a box worth of Takis chips for $20(how many bags does not matter). You want to sell

Answer 1

You would need to sell at least 11 bags in order to make $68 profit. In total, to earn back what you spent on the box originally, you would need to make $88, which is how much 11 bags costs. If you make $88, then you have earned back the $20 spent on the box, and made the $68 profit.
