# The equation for a demand curve is What is the elasticity in moving from quantity of 5 to a quantity of 6?

To determine

Calculate the elasticity of demand for the following demand function when quantity rises from 5 units to 6 units.

P= 48 - 3Q.

Explanation

We will first find the price at quantity of 5 units.

P = 48 - 3QP = 48- 3×5P = 48 - 15P = $33 Now, we will find the price at quantity of 6 units. P = 48 - 3QP = 48- 3×6P = 48 - 18P =$30

Now, we can calculate the elasticity of demand with the foll
