Elastic demand-demand that is very sensitive to a change in price E>1 the product is not a necessity, and their are available substitutes (cookies)

InElastic demand-Is not very sensitive to a change in price E<1 the product is a necessity, their are few to no substitutes, people will buy no matter what (water)

Unit/Unitary elastic-E=1

Formula's

TFC + TVC = TC

AFC + AVC = ATC

TFC/Q = AFC

TVC/Q = AVC

TC/Q = ATC

TFC = AFC x Q

TVC = AVC x Q

MC = new TC - old TC

Price of Elasticity of Demand (PED)

Step 1: Quantity

New Quantity-Old Quantity/old quantity

Step 2: Price

New Price- Old Price/ old price

Step 3: PED

% Δ  in quantity demanded/ %Δ in price = PED

Total Revenue-Total amount of  money a firm receives from selling goods and services
