Please help me answer this. Thank you so much.

Subway v/s Big Mac

When subway launched it started taking market share of McDonald because its food is regarded

as fresh, healthy, on spot and made as per customer's taste and preference. In 2003, McDonald then replaced its traditional question "will you have fries with that" to "will you have an apple with that" as a part of its major reorientation of the product to match its customer's preferences.

questions;

a) Explain why McDonald has made this change? Refer to the conditions of demand of BigMac?

b) What combination of two graphs (McDonald and Subway) would you use to illustrate the

above fast food situation? (movement along the curve or shift)

c) What factors were responsible for the changes in the fast food market?

d) What would happen if they didn't make any such changes?

e) According to you, how was the impact of this change in strategy of McDonald?
