Suppose you are running a lemonade stand at your local farmer's market and you want to be able to estimate how much it is going to cost you to run your business. You have to consider two types of costs: Fixed Costs and Variable Costs.

Write a linear equation for the total cost of having your lemonade stand if it costs you $50 to have your stand at the market and your lemons cost you $0.30 each.

The revenue you earn from selling your lemonade can also be shown as a linear function. Suppose you sell glasses of lemonade for $1.25 per glass.

Write the equation that shows how much money you would take in on any given day.

Essentially, profit is found by taking the total money you make from selling lemonade and subtracting your total costs. For example, if you took in $450 in sales for a day and it cost you $275 to make your lemonade, you would profit $175 for your days work.
Write a simplified equation for your profit by subtracting your cost equation for question 1 from your revenue equation for question 2.
