A. Independent variable: number of rubber stamps n sold. Dependent variable: F(n), the total sales.
B. Only whole numbers. It is impossible to have negative and/or fractional stamps.
C. F(n) = $4.95n, which is 4.95 times n.
So, plugin 5 for n
F(n) = $24.75

The correct answer is 19.1
EXPLANATION
The perimeter of triangle OQR is the sum of the distance around the triangle.
Thus,
We can observe that two of the angles are equal.
The angles that are equal measures 62° each.
Therefore triangle OQR is an isosceles triangle. This means that
Hence,
units.
