Suppose that the relationship between price, P, and quantity, Q. is given by the equation Q-60-3P. Which of the following equations correctly represents solving Q= 60-3P for P? OP=20-0 P=60-30 P=20-30 P=60+Q P=60-Q Plot the relationship between P and Q on the following graph. Note: Price (P) is on the vertical axis and quantity (Q) is on the horizontal axis. 40 35 30 30 25 PRICE 20 20 15 16 10 5 5 10 15 15 20 25 30 35 40
