to decide on the number of people to employ based on the following short-run production function: Q = 12L – 0.5L2 Where Q is the number of cuts per week and L is the number of workers. Suppose the price of a haircut is RM9‚ how many people should be hired if she pays each worker RM60 per week. 2. Based on a consulting economist report‚ the demand function for Formula 1 stickers by two individuals‚ (assuming the market has only 2 individuals) Q1 = 16 - 4P

Note: Write down all of your calculations. According to our Textbooks and given information‚ When P = 8000‚ A = 64‚ PX = 9000‚ I = 5000‚ we can use regression equation‚ QD = 20000 - 10*8000 + 1500*64 + 5*9000 + 10*5000 = 131‚000 Price elasticity = (P/Q)*(dQ/dP) From regression equation‚ dQ/dP = -10.
