Best ResponseYou've already chosen the best response.0The company discovered that it costs $28 to produce 2 camera cases, $50 to produce 4 camera cases, and $140 to produce 10 camera cases. Using the quadratic function, find the cost of producing 12 cameras.

Best ResponseYou've already chosen the best response.0ok lets liken this to acceleration. You are in a car. You see that you went 28 yards in 2 seconds. 50 yards in 4 seconds and 140 yards in 10 seconds. What is your acceleration?

Best ResponseYou've already chosen the best response.0wait, are you sure that it costs $140 to produce 10 camera cases?

Best ResponseYou've already chosen the best response.0okay then scrap the acceleration analogy.

Best ResponseYou've already chosen the best response.0and wastage is y. Then we can say total production cost P = YC^2+XCZ where C is the number of cameras.

Best ResponseYou've already chosen the best response.0so plug in the three values of production cost and number of camera cases in the equation above and solve for X,Y and Z

Best ResponseYou've already chosen the best response.0or, lets say the quadratic equation to define the number of camera cases was P = ax^2+bx+c , where x is the number of cases and P is the total production cost. plug in the three values of P and x. and solve for a,b,c. three equations three unknowns. easy as pie.
