I think the correct answer to this would be:
“A health report showing eating pizza reduces stress”
<span>If health news about pizza reducing stress would come
out, people’s willingness to buy pizza would definitely increase. This is
because of the additional positive reinforcer, reducing stress, associated with
the great taste of pizza that people would definitely buy this.</span>
Answer:
- 0.80
Explanation:
Price elasticity of demand describes the extent to which the quantity demanded of good X changes as result of a change in its own price.
The midpoint formula for price elasticity of demand is presented and used as follows:
Percentage change in quantity = %ΔQ = [Q2 - Q1] / [(Q2 + Q1) ÷ 2] × 100
Percentage change in quantity = %ΔP = [P2 - P1] / [(P2 + P1) ÷ 2] × 100
Midpoint price elasticity of demand = %ΔQ / %ΔP
Where:
Q2 = New quantity of good X = 150
Q1 = Initial quantity of good X = 100
P2 = New price of good X = $6
P1 = Initial price of good X = $10
Therefore,
Percentage change in quantity = %ΔQ = [150 - 100] / [(150 + 100) ÷ 2] × 100
= [50/(250 ÷ 2)] × 100
= (50/125) × 100
= 40.00%
Percentage change in quantity = %ΔP = [$6 - $10] / [($6 + $10) ÷ 2] × 100
= [-$4/($16 ÷ $2)] × 100
= (-$4/$8) × 100
= - 50.00%
Price elasticity of demand = 40% / 50% = - 0.80
The elasticity of demand of -0.80 less than 1. That indicate that the quantity demand is inelastic. That is the change in the degree of change in the quantity demanded of good X is lower than the degree of change in its price.
