1) The following graph shows the depreciation for the corporate airplane from 2006
to 2009. The plane was purchased new in 2006; therefore, x = 0 represents the
year 2006.
X – axis (horizontal) = years starting from 0 = 2006 and increasing by 0.5 years
Y – axis (vertical) = price in $ amounts from 24,000 to 240,000
a) List the coordinates of two points on the graph in (x, y) form. The numbers on
the horizontal axis are 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, and 3.5.
(___, ___),(___, ___)
b) Find the slope (rate of depreciation) of this line:
Answer:
Show your work here:
c) Find the linear equation of this line in slope-intercept form.
Answer:
Show or explain your work here:
d) If the rate of depreciation continues at the present rate, what will be the plane’s
value in the year 2017? Show how to use the linear equation from part c) to
obtain your answer.
Answer:
Show or explain your work here:
e) If the trend continued, in how many years would the plane’s value be $48000?

2) Suppose that the width of a rectangle is 5 inches shorter than the length and that
the perimeter of the rectangle is 50 inches. The formula for the perimeter of a
rectangle is P=2L+2W.
a) Set up an equation for the perimeter involving only L, the length of the rectangle.
Answer:
b) Solve this linear equation algebraically to find the length of the rectangle. Find
the width as well.
Answer: Length ______, Width ______
Show your work here:
c) Using the same width as your answer from part b), find a new perimeter if the
new length is 4 less than three times the width.
Answer:
Explain your work here in one or two sentences:
3) A marketing group developing online ad space is offering two payment options:
Option 1: $210 set up fee plus $10/inch of the ad
Option 2: No set up fee but $25/inch of the ad
Let x = inches of the proposed ad, for example, x = 2 for a column ad that is 2
inches long.
a) Write a mathematical model representing the total ad cost, C, in terms of
x for the following:
Option 1: C=_________________
Option 2: C=_________________
b) How many inches of ad space would need to be purchased for option 1
to be less than option 2? Set up an inequality and show your work
algebraically using the information in part a).
Answer:
Show your work here:
c) Summarize your findings in a brief sentence.
Answer:
4) Graph the equations on separate graphs by completing the tables and plotting
the points. You may use Excel or another web-based graphing utility.
