answer all parts for thumbs up

for probs a-c consider the real-world elasticity question that Netflix faces. In January 2019 Netflix increases their price from $10.99 to $12.99 (you can round to 11 and 13). 1a. Netflix expects that the number of their memberships (quantity demanded) will decrease from 30 million to 28 million memberships. First, assuming a linear relationship (a straight line) graph what Netflix thinks their demand curve looks like. Next, calculate what Netflix estimates their price elasticity of demand to be.

b. Instead assume that after the price change the number of memberships decreases from 30 million to 20 million memberships. Again, assuming a linear relationship (a straight line) graph the demand curve and calculate elasticity of demand? c. From your calculations in 8 and 9 explain why the elasticity of demand is a very important concept for executives to understand.
