paper. 1. One of the important factors to consider in break-even analysis. a. Fixed cost c. Variable cost b. Revenue d. Total cost 2. It is when the business neither makes a profit nor a loss. a. Break-even c. Profit and loss analysis b. Profit = Loss d. Cost control analysis For questions 3 to 6 Suppose that the total cost of a business is TC = 30+ 2x, and the unit price of a certain commodity is p= 15-x. 3. Find the revenue function C. R = px = (15x - x) x = 15 - x c. R = px = (15x - x ) x = 2x d. R = px = ( 15-x) x= 15x - x d. R = px = (15 - x) x = 15x - 2x 4. Determine the profit function e.P = R - TC = (15x - x ) - (30+2x) = x + 13x - 30 f.P = R - TC = (15x - x) - ( 30+2x) = 2x + 13x - 30 g.P = R - TC = (15x - 2x) - ( 30+x) = 2 + 13x -30 h.P = R - TC = (15 - 2x) - ( 30x+2x) = 2x + 13-30 5. Find the breakeven point b. (4,37) (15, 30) c. (3,36) (10, 50) c. (5, 35) (10,40) d. (2. 42) (20.40) 6. How many units are needed to earn profit of P 10? a. 5 or 8 c. 6 or 9 b. 6 or 7 d. 7 or 10
