Derek and Maria are now trying to predict how much money they will raise for their club from the car wash. They determine their costs to be about $0.50 in materials to wash each car as well as their initial start-up costs of $220. They model their costs using the function c(x) 0.5x + 220. They will charge $10 for each car wash. Additionally they received a $50 donation from one of the member's parents. They model their revenue using the function r(x) = 10x + 50. = The profit from the car wash, p(x), can be determined by finding r(x) - c(x). Part A: Find the function that represents the profit from the car wash. clv (10x+50) 10.5% 1,229, 1470 Part B: What is the meaning of the y-intercept of p(x) in terms of the situation?
