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

Find The Revenue If 18 Units Are Sold Round To Two Decimal Places class=

Sagot :

The revenue function is:

[tex]R(x)=x\cdot p(x)[/tex]

where p(x) is given by:

[tex]p(x)=27(5)^{\frac{-x}{6}}[/tex]

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

[tex]p(18)=27(5)^{-\frac{18}{6}}=27(5)^{-3}=\frac{27}{125}[/tex]

Then, for R(x):

[tex]R(18)=18\cdot p(18)=18\cdot\frac{27}{125}\approx3.89[/tex]

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