It's a linear function with y-intercept = 12.

The slope-intercept form:

f(x)=mx+b\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

Let's read the coordinates of two points on the graph:

(2, 15) and (4, 18)

Substitute to the formula of a slope:

m=\dfrac{18-15}{4-2}=\dfrac{3}{2}=1.5

We have the equation of a line:

\boxed{f(x)=1.5x+12}

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

Substitute:

f(1)=1.5(1)+12=13.5

f(20)=1.5(20)+12=30+12=42

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

\$13.50-\$12.00=\$1.50

The total cost is $42.00 after 20 visits.

The unit measurement of the a volume in mm is mm³(millimetres cube.)

<h3>How to find volume ?</h3>

Volume is is defined as the space occupied within the boundaries. The objects are usually solid objects.

The volume of a 3 dimensional figure is the product of the base area and the height.

Therefore, the units of volume is measured in cubic units.

The volume of a prism with side lengths measured in millimetres is 20.

Therefore, the measurement can be represented as follows:

20 mm³
