Demand the demand function for a product is given by
p = 8000(1 - 5/5 + e^-0.002x)
where p is the price per unit (in dollars) and x is the number of units sold. find the numbers of units sold for prices of (a) p = $200 and (b) p = $800.

a)

b)

Step-by-step explanation:

For this case we have the following function:

We can solve for x like this. First we can reorder the expression like this:

Now we can apply natura log on both sids and we got:

And if we solve for x we got:

Part a

For this case we can replace P = 200 and see what we got for x like this:

Part b

For this case we can replace P = 800 and see what we got for x like this:
