In a survey of nearly 200 senior marketing managers, 71 percent responded that they found a customer satisfaction metric very useful in managing and monitoring their businesses. Here are the top six reasons why customer satisfaction is so important:
1 When the price elasticity of demand for a good is unit (or unitary) elastic (E d = 1), the percentage change in quantity is equal to that in price, so a change in price will not affect total revenue.2  When the price elasticity of demand for a good is relatively elastic d. When the price elasticity of demand for a good is relatively elastic d. 2  When the price elasticity of demand for a good is perfectly elastic (E d is â â), any increase in the price, no matter how small, will cause demand for the good to drop to zero. 3  Hence, when the price is raised, the total revenue falls to zero.
So we have, when we had, based on the way we calculated it, it's 67% increase in price, we had a 46% increase in quantity supplied. So this is a 46% increase in quantity supplied. And so we could see it's going to be 40. Our elasticity of supply is going to be 46% over 67%. So it's going to be something less than 1. So that's going to be that divided by-- it's actually 0.6666 and it keeps going on forever-- gets us to 0.69. So this gives us an elasticity of supply of 0.69. And maybe I should say approximately 0.69, which tells us that we get a smaller percent. At least at this price point right over here, we get a smaller percent change in quantity supplied than our percent change in price.
