Refer to Example 1 in this section. Notice that if the price charged for the calculators is or , then the revenue is . It is easy to explain why revenue would be if the price charged were , but how can revenue be if the price charged ?
Why the Revenue obtained by selling the calculators will become if the price charged per calculator is .
Answer to Problem 31AYU
Here, we can see that the revenue is the product of the number of calculators sold and the price charged per calculator.
The number of calculator sold is given by the equation .
In this equation, if we substitute , we can see that
.
This means that if the price of per calculator is or more, there will be no calculators sold.
Thus, if there is no selling then there will be no revenue.
Thus, when then cost of per calculator is the revenue will be .
