47
Demand Function

48
The current price of product a is 7 pesos the intercept of the demand curve is 4 the slope is 0.25 compute how much of product a will be demanded by consumer z
Qd = a-bP
=4 - 0.25(7)
=4-1.75
= 2.25 units of Product A

constant
54
Supply Schedule

Supply Elasticity
Measures the degree of supplies responsiveness to a given price change.
Es= percentage change in quantity supplied/percentage change in price
