Imagine you buy and sell bicycles from your small store. One day, you receive a customer, Yuya, who tells you the following: ``I want to buy a bicycle whose price is \$200, but I am only willing to pay \$100 for it.'' You know that the total cost of each bicycle is \$160, with \$70 the sum of variable costs and \$90 the sum of \emph{allocated} fixed costs.
Next paragraph text follows here:%%If I remove this enter mark, then it works
\begin{enumerate}
\item Would you sell the bicycle for \$100? (Ignore taxes when making your calculations.)
\end{enumerate}
}
\end{document}
O código acima funciona bem, se eu remover o para enter, mas tiver muitos parágrafos de texto, como posso corrigir esse problema? Por favor, avise...
