He will use all of his birthday money and all of the money he earns from his paper route. In how many weeks will he be able to buy the mountain bike?$\mathrm{(A)}\ 24 \qquad\mathrm{(B)}\ 25 \qquad\mathrm{(C)}\ 26 \qquad\mathrm{(D)}\ 27 \qquad\mathrm{(E)}\ 28$== Solution ==

Let$ (Error compiling LaTeX. Unknown error_msg)x$be the number of weeks.

Thus, we have the equation$ (Error compiling LaTeX. Unknown error_msg)50 + 35 + 15 + 16x = 500$.

Simplify,$ (Error compiling LaTeX. Unknown error_msg)100 + 16x = 500$$ (Error compiling LaTeX. Unknown error_msg)16x = 400$$ (Error compiling LaTeX. Unknown error_msg)x = 25$The answer is$ \boxed{\textbf{(B)}\ 25} $
