Question 1. a) The initial price of a chip is $410 and at this price the number of chips sold per ear equal 36 million. However, when the price of a chip falls to $390 the quantity demanded to 44 million chips a year. Using this information calculate the price of elasticity of demand.
b) If the price falls from $500 a chip to $300 a chip and the quantity demanded rises from 0 to 80 million chips per year respectively, what is the price elasticity of demand.

Your advice is needed for, the following questions:
(Change in Q / sum of q1+q2/ 2) divided by (change in p / sum of p1 +p2 /2) mid point formula
10 / (60+50/2) divided by (100 / (100+200/2) = - 0.28 100 -200 6000
- 0.56 10 000
- 1 12000
- 1.8 12000

a) What will happen to Intel's total revenue if the price of a chip falls from $400 to S300? Revenue stays the same
b) What will happen to Intel's total revenue if the price of a chip falls from $300 toS200?
c). What is the price at which Intel's total revenue is maximized?
d) At an average price of $350, is the hand for chips elastic or inelastic? Use the total revenue test and your answer to part a) to answer this question.
e) At an averageprice of $250, is the demand for chips elastic or inelastic? use the total revenue test and your answer to part b) to answer this question.
f) What is the elasticity of demand for chips at the price that maximizes Intel's revenue?
