Example:
A business owner is trying to determine how many products she needs to sell in order to make a profit. She knows that her costs are $10 per product and that she sells each product for $15. She can use the following linear equation to determine the number of products she needs to sell:
15x - 10x = 1000
Solving for x, we get:
5x = 1000
x = 200
Therefore, the business owner needs to sell 200 products in order to make a profit.
