This video explains how to solve the word problem below. You should try to solve the problem before watching the video and click "Reveal Answer" to see if you are correct.
Problem: Kaden owns and operates a lemonade stand and is trying to find a model to predict their profits. Kaden knows that the weekly profit of the lemonade stand can be modeled by a linear function. Based on previous weeks, Kaden knows that selling 350 lemonades earns a profit of $375 for the week while selling 550 lemonades earns a profit of $875 for the week. Determine the linear profit function for Kaden's lemonade stand.
Profit \(=P(x)=2.5x-500\)
