From the schedule provided below calculate the total revenue, demand curve and the price elasticity of demand:

We calculate the total revenues by simply adding one particular marginal revenue with the previous one. For example to calculate total revenue at quantity=2 we add the marginal revenue 6 with the previous marginal revenue that is 10 and we get total revenue at 2 units of quantity= 16. Like this we have to do for all the quantity units. For the quantity unit = 1, since there is no previous marginal revenue to it, we assume the previous marginal revenue was zero and thus put 10 as total revenue for quantity=1. The values of total revenues are given in the table below:

To find out the demand curve we will first calculate the prices with respect to each unit of quantity. This can be done by dividing each total revenue values with the quantity. The values of prices are given below:

Plotting each value of price-quantity combination we will get the demand curve which will look like the curve given above.

From the curve we can see that the curve is a flatter curve which suggests that the price elasticity of demand will be greater than one, that is this is an elastic curve.
