Application 1. Suppose the cost expenditure needed to produce 100 units of a product is P5,000 and the cost of producing 180 units is P9,000. If the linear relationship exists between the cost y and output x, describe this in terms of a linear equation. 2. Given the points(10,300) and (20,225), a. Find the equation of the line passing through the given points b. Express the equation in slope intercept form ( y- y1) = 21 21 (x -x1) c. Assuming that x represents the number of articles sold when y pesos is the price of each article, graph the function and interpret the meaning of its slope when the function is defined in the first quadrant only. For some Agricultural product products n a developing country ,the estimated demand was x = 224.125 - 0.097 p and the supply was x =-49.375 + 1.721 p a. Find the equilibrium price and quantity. b. Make a graph of the demand and supply functions on the same axes and mark the equilibrium point. 4. A producer sells items at P1.20 each if his cost of production is given by C(x) =0.60x +420 where x is the number of items sold ,find the breakeven point .If he can change his cost function to C(x) = 0.48x + 432, would it be to his advantage to do so? Why?
