everyday examples
The price of PS3 has decreased from $300 dollars when it first came out to currently being $150. Likewise, Sony has decreased its quantity supplied from 4 million units to 2 million units. What is the elasticity of supply, and determine whether the product is elastic, inelastic or unitary?

QS 4-2/4 = 2/4 = .5 x 100 = 50
P 300-150/300=150/300 = .5 x 100 = 50
QS/P or E 50/50 = 1 Unitary
