Question: Suppose the two price and quantity combinations (Q=10, P = 31) and (Q = 202, P = 3) lie on the market demand curve. Solve

Suppose the two price and quantity combinations (Q=10, P = 31) and (Q = 202, P = 3) lie on the market demand curve.

Solve for the market demand curve equation in the form

P = a - bQ

What is a + b?

Enter your answer as a number to 2 decimal places.

NOTE: ADD THE ABSOLUTE VALUES OF a AND b TOGETHER, E.G. IF P = 100 - 5Q, THEN a + b = 105.
