#### Solution Preview

a. When P = \$20 WHAT is the difference, if any between Qd and Qs
- Insert P = \$20 in demand and supply curve expressions
Qd = 25 - 20 = 5
Qs = 10 + 2*20 = 50
Difference is 50 - 5 = 45

b. When P= 43, what is the difference if any between ...

#### Solution Summary

Solution shows the equilibrium values of P and Q.
