To find company X’s profit for a given year, first find the year on the horizontal scale of the graph and then draw a line
straight up until you reach the dot directly above the year. Then draw a line straight to the left from the dot until you reach the
vertical scale on the left side of the graph. The number on the left is the profit for that year. The most profitable year was
1986, when the profit was $110 million. The least profitable year was 1984, when the profit was $80 million. So all we have
to do is subtract: 110 million − 80 million = $30 million, choice (J).
B
We can assume that the wall is rectangular, so the area of the wall is base times height. We are given that the height is 12 feet
and the area is 132 square feet, so we can express this in an equation: 132 = 12 × base. If we divide both sides by 12, we
find that the base is equal to 132 ÷ 12, or 11 feet. The perimeter of a rectangle is the sum of the lengths of the four sides, so
the perimeter of this wall is 11 + 12 + 11 + 12, or 46 feet, choice (B).

G
We don’t have enough information to figure out what a or b is individually, but we can figure out what the sum of a and b is.
Altogether, the three angles marked a and the three angles marked b add up to make a straight line, or a 180° angle. So we can
say that 3 a + 3b = 180. Then we can divide both sides by 3 and find that a + b = 180 ÷ 3, or 60, choice (G).

D
You can just add these numbers up. But you can also eliminate choices (A) and (B) because they are too small. Since several
numbers are being added to 400,000, we know that the answer will have to be greater than 400,000. The correct answer is
(D).

H
How many times does 24 go into 200? Calculate 200 ÷ 24 = 8 with a remainder of 8, so Doris can fill 8 boxes of chocolates
with eight left over.
66.
C
This figure is made up of two triangles put together. Since all of the line segments are the same length, these triangles are
equilateral. In an equilateral triangle, each angle is 60°. Angle ABC is made up of angle ABD and angle CBD, which each
measure 60°, so the measure of angle ABC = 60° + 60° = 120°, choice (C).

J
To solve this problem, we will try to make the expression in the question look like each of the answer choices until we find
one that works. To turn 483 into 48.3, we would have to multiply it by 0.1. To keep the expression balanced, we would then
have to multiply 0.0793 by 10, which is 0.793, so our expression would read 48.3 × 0.793. There are two answer choices
that include 48.3—choices (F) and (J)—and neither of them includes 0.793, so we can eliminate these two choices. To make
483 look like 4.83, we would have to multiply it by 0.01. To keep the expression balanced, we would have to multiply
0.0793 by 100. So our expression would read 4.83 × 7.93. This is choice (K).
