It's a linear function with y-intercept = 12.
The slope-intercept form:

Let's read the coordinates of two points on the graph:
(2, 15) and (4, 18)
Substitute to the formula of a slope:

We have the equation of a line:

We need calculate the value of function for x = 1 and x = 20.
Substitute:


$12 is the "Fixed Fee", therefore the discounted entrance fee to the art museum is

The total cost is $42.00 after 20 visits.

Answer:
10 black marbles

If you turn 1/4 into a decimal, which is 0.25, all you have to do then is 0.25 + 8 x 8 + 6 + 8 = 78.25 Hope this helps!!
In Step 2, Lara did not ensure that the second diamter was perpendicualr to the first diameter she drew.
The correct steps should be:
Step 1: Use the straightedge to draw a diameter of the circle. Label the points at which the diameter touches the circle as A and B.
Step 2: Draw a second diameter <em>perpendicular to the first diameter</em>. Label the points at which the second diameter touches the circle as C and D.
Step 3: Join the end points of the two diameters to form a square.
