Section B - Case 1: AeroDrone Tech

AeroDrone Tech is an agricultural technology startup developing the 'AgriScout', a drone designed to monitor crop health. Market research indicates that large-scale farms would be willing to pay $1,200 for such a drone. AeroDrone's investors require a profit margin of 20% on the selling price. The current estimated production cost of the AgriScout is $1,050.

AeroDrone's marketing team estimates that at a price of $1,200, demand will be 5,000 units. If the price is increased to $1,300, demand will fall to 4,000 units.

What is the Price Elasticity of Demand (PED) for the AgriScout? (Use the basic PED formula: % change in quantity / % change in price)

Answer options:

A.

-0.42

B.

-2.4

C.

-1.2

D.

-4.0

How to approach this question

1. Calculate % change in quantity: (New Q - Old Q) / Old Q. 2. Calculate % change in price: (New P - Old P) / Old P. 3. Divide % change in Q by % change in P.

Full Answer

B.-2.4✓ Correct
% Change in Quantity = (4,000 - 5,000) / 5,000 = -20% (-0.20). % Change in Price = ($1,300 - $1,200) / $1,200 = +8.33% (+0.08333). PED = -0.20 / 0.08333 = -2.4. Because the absolute value is > 1, demand is elastic.

Common mistakes

Inverting the formula (Price change / Quantity change).
