Question 1.

If the quantity of soccer balls demanded is represented by the demand equation QD = 80 - 2P, then to solve for the price of soccer balls, the equation would be rewritten as

P = 1.6QD + 80.

P = 80 - QD.

P = 40 - 0.5QD.

P = QD + 160.

Question 2.

If the quantity of donuts supplied is represented by the supply equation QS = -15 + 5P, then to solve for the price of donuts, the equation would be rewritten as

P = 0.2QS + 3.

P = 5QS + 75.

P = QS - 7.5.

P = 15 - 0.5QS.
