Bicycles and Motorcycles Sales Problem

In a small town, the number of bicycles and motorcycles sold in a year is represented by the following equations:

Let $b$ be the number of bicycles sold and $m$ be the number of motorcycles sold. The equations are:

• 1. $b + m = 500$
• 2. $3b + 5m = 2500$

Using the above equations, determine the number of bicycles sold in that year.
