11 points total - The supply curve for Apple HomePod speakers is Q= 100+4P

1. 3 points - Compute the price elasticity of supply in the part of the curve where the price increases from $2 to $4. Do you find Q* increases or decreases after the price increase? Does this make sense? Why (in a few words)?
2. 2 points - Is that area of the curve elastic or inelastic? How can you tell (in a few words)?
3. 1 point - Compute the price elasticity of supply in the part of the curve where the price increases from $10 to $12.
4. 2 points - Is the area of the curve in part (c) more or less elastic than the area you calculated in parts (a) and (b)? How can you tell (in a few words)?
5. 3 points - How can there be different elasticity values along the same supply curve for the same amount of change in price? Explain

Note: do not round for intermediate steps and use at least 3 digits after the decimal point for your final answer (i.e. three significant digits)
