Answer:
$302,500
Step-by-step explanation:
If cost (C) = $7, then Sales (S) = 37,500 units
If cost (C) = $15, then Sales (S) = 17,500 units
The slope of the linear relationship between units sold and cost is:

The linear equation that describes this relationship is:

The revenue function is given by:

The cost at which the derivative of the revenue equals zero is the cost that yields the maximum revenue.

The optimal cost is $11, therefore, the maximum revenue is:

A=πr^2
A=3.14(11^2)
A=3.14(121)
A=379.94 which is simplfied to 380
