Answer:
17 feet
Step-by-step explanation:
Since a square has 4 sides, you have to do 68 / 4 to find one of the sides.
68/4 = 17
And to check, if you add up all sides...
17+17+17+17 = 68
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:

C, 120 units2 is the answer
