Question

Find the revenue if 18 units are sold. Round to two decimal places.

Answer 1

The revenue function is:

`R(x)=x\cdot p(x)`

where p(x) is given by:

`p(x)=27(5)^{(-x)/(6)}`

For x=18, you obtain for p(x):

`p(18)=27(5)^{-(18)/(6)}=27(5)^(-3)=(27)/(125)`

Then, for R(x):

`R(18)=18\cdot p(18)=18\cdot(27)/(125)\approx3.89`

Then, if 18 units are sold the revenue is approximately 3.89 dollars.
