Answer #1

Answer to the question:

Option a: Decreases as price decreases.

Explanation: The formula to find the point elasticity of demand is:

Here LS= Lower segment and US= Upper Segment.

Refer to the following diagram:

The red curve is the demand curve. As the price decreases, the quantity increases. And we move down along the demand curve. That will cause the value of the upper segmet to rise and the lower segment to decline, causes the elasticity of demand to fall.

In the market for widgets, the supply curve is the typical upward-sloping straight line, and the demand curve is the typical downward-sloping straight line. The equilibrium quantity in the market for widgets is 200 per month when there is no tax. Then a tax of $5 per widget is imposed. The price paid by buyers increases by $2 and the after-tax price received by sellers falls by $3. The government is able to raise $750 per month in revenue from...
