Stuck on candy bowl fraction I am really stuck on this problem because I'm not even sure where to start.
Larissa has a bowl of candies. On the first day, she eats 1/2 of the candies plus one more. On the second day, she eats 1/3 of the remaining candies plus one more.  On the third day, she eats 1/5 of the remaining candies plus one more.  On the fourth day she eats the three remaining candies.  How many candies did she have at the start?

Let $x$ be the number of candies to start with ... then 
\begin{eqnarray*}
\frac{1}{5} \left(\frac{1}{3} \left(\frac{x}{2} -1 \right) -1 \right) -1 =3.
\end{eqnarray*}
So ...
