Answer: $25
Explanation:
The full economic price is the the dollar amount that a business gets as a result of a price ceiling and will be the price that equates the Quantity demanded to that supplied given the price ceiling.
Quantity demanded = 100 - 2P
= 100 - 2 * 15
= $70
Quantity Supplied = 5 + 3 * P
= 5 + 3 * 15
= $50
Qs = Qd
50 = 100 - 2P
2P = 50
P = $25
