### Computing Total and Marginal Revenue

4. Below is a demand curve. From
it, compute total revenue and marginal revenue. Put your answers in
the yellow cells, entering just a number--the dollar sign is already
there. When you are finished, click the "Check Answers" button and
see how you did. If you are totally lost, or totally lazy, click the
"I cannot do it!" button and I will fill in the answers for you.
(Hint: Do the Total Revenue column first, then the Marginal Revenue
column. Notice that the first Marginal Revenue box is between 0 and 1
units of output and the last is between 4 and 5 units of output.)

### Computing Total and Average Revenue

5. Below is a table showing sales
and marginal revenue. Compute total revenue and average revenue. Put
your answers in the yellow cells, entering just a number--the dollar
sign is already there. When you are finished, click the "Check
Answers" button and see how you did. If you are totally lost, or
totally lazy, click the "I cannot do it!" button and I will fill in
the answers for you. (Hint: Do the Total Revenue column first, then
the Average Revenue column.)
