Answer:

Explanation:
Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.
If the company has a fixed cost (fixed being a keyword) of $700, then that cost will be a steady value before they even start to manufacture the bicycles. Afterwards they have to spend $50 on each bicycle they produce. Since we do not know the amount of bicycles that have been produced we can use the variable x to represent this.

The equation above states that the company pays $700 plus $50 for every bike produced which comes out to a total of y.
