We can solve for "p" to know the function for price. 

So, we subtract both sides by 0.45x. 

`p + 0.45x - 0.45x = 6 - 0.45x`

`p = -0.45x + 6`

We know that revenue = price * amount of units sold. 

So, we will have:

`r = (-0.45x + 6)(x) `

` `

Use Distributive property.

`r = -0.45x^2 + 6x`  

Take the derivative of both sides. 

`r' = -0.9x + 6` 

Equate it to zero. 

`-0.9x + 6 = 0`

Subtract both sides by 6.

`-0.9x = -6`

Divide both sides by -0.9.

`x = 6.67 or 7.0`
