Introduction to Graphs and Charts
You may be tempted to write the numbers as you do your arithmetic (3.5 million =
3,500,000), but this is unnecessary since it often is on graphs that use large numbers.
Because all the measurements are in millions, adding zeros does not add precision
to the numbers.
The correct answer is B. Referring to the Monster Burger bars, you can see that
gross receipts are as follows: 1994 = 2.5 million, 1995 = 2.5 million, 1996 = 3.4
million (if you have trouble seeing how the bars line up with the numbers, you can
use your answer sheet as a straightedge to determine a number such as this last
one). Totaling the receipts for all three years, you get 8.4.
Referring to the Pizza in a Pot bars, you can see that gross receipts are as follows:
1994 = 1 million, 1995 = 2.1 million, 1996 = 3 million (don’t designate numbers
beyond the nearest tenth, because the graph numbers and the answer choices prescribe
no greater accuracy than this). Totaling the receipts for all three years, you
get 6.1 million.
So Monster Burger exceeds Pizza in a Pot by 2.3 million. The answer that best
approximates this figure is B.
6. From 1995 to 1996, the percent increase in receipts for Pizza in a Pot
exceeded the percent increase for Monster Burger by approximately how
much?
A. 0%
B. 2%
C. 10%
D. 15%
E. 43%
The correct answer is C. Graph questions on the CBEST may ask you to calculate
percent increase or percent decrease. The formula for figuring either of these is
the same:
amount of the change
the startingamount (followsthe word "from")
In this case, you may first calculate the percent increase for Monster Burger:
Gross receipts in 1995 = 2.5 million
Gross receipts in 1996 = 3.4 million
Amount of the change = 0.9 million
