On Tuesday 27% of the customers who bought gas at a gas station made additional purchases. There were 300 customers who bought gas. How many of these 300 customers made additional purchases?
Responses
A 219219
B 2727
C 273273
D 8181
To find the number of customers who made additional purchases, we need to multiply the total number of customers who bought gas by the percentage of customers who made additional purchases:
300 x 0.27 = 81
Therefore, 81 of the 300 customers who bought gas made additional purchases. The answer is D.
A grocery clerk put only packages of flour tortillas and packages of corn tortillas on a shelf. The ratio of the number of flour tortillas to the number of packages on the shelf was 5 to 9. Which number could be the number of packages of corn tortillas the clerk put on the shelf?
Responses
A 3232
B 1818
C 1414
D 23
Let's call the number of packages of flour tortillas "5x" and the number of packages of corn tortillas "9x". We know that the total number of packages on the shelf is the sum of these:
Total number of packages = 5x + 9x = 14x
We also know that the total number of packages on the shelf is a certain number, but we don't know what that number is. Therefore, we can set up an equation using one of the answer choices and see if we can solve for x.
Let's try choice D: If there were 23 packages of corn tortillas on the shelf, then the total number of packages would be:
Total number of packages = 5x + 9x = 14x = 23
Solving for x:
x = 23/14
x ≈ 1.64
Since x must be a whole number (you can't have a fraction of a package), this answer choice does not work.
Let's try the next answer choice: If there were 14 packages of corn tortillas on the shelf, then the total number of packages would be:
Total number of packages = 5x + 9x = 14x = 14
Solving for x:
x = 1
This works! If there was only 1 package of flour tortillas on the shelf and 9 packages of corn tortillas, then the ratio of flour tortillas to the total number of packages would be 5:9.
Therefore, the answer is C: 14.

Question
Four points are graphed on the coordinate grid. Which point is best represented by the ordered pair ( -5.5, 2)?
Responses
A Point SPoint S
B Point RPoint R
C Point VPoint V
D Point W
The ordered pair (-5.5, 2) means that the point has an x-coordinate of -5.5 and a y-coordinate of 2. We can look at the four points on the coordinate grid and see which one matches this description.
If we look at Point S, it has an x-coordinate of -4 and a y-coordinate of 2. Point R has an x-coordinate of -5 and a y-coordinate of -2. Point V has an x-coordinate of 3 and a y-coordinate of 2.
Therefore, the only point that matches the description of having an x-coordinate of -5.5 and a y-coordinate of 2 is Point W.
The answer is D: Point W.

Question
The list shows the numbers of employees in the seven departments at a company.
14, 23, 54, 30, 26, 17, 26
What is the range of the numbers of employees in these departments?
Responses
A 99
B 4040
C 1212
D 6
To find the range of a set of numbers, you need to subtract the smallest number from the largest number.
The smallest number in the list is 14 and the largest number is 54.
Range = Largest number - Smallest number
Range = 54 - 14
Range = 40
Therefore, the range of the numbers of employees in these departments is 40, and the answer is B.
The area of a rectangle is 55.5 square inches. The height of the rectangle is 15 inches. What is the length of the base of the rectangle in inches?
Responses
A 40.5 in40.5 in
B 6.5 in6.5 in
C 832.5 in832.5 in
D 3.7 in
To find the length of the base of the rectangle, we need to divide the area of the rectangle by its height:
Length of base = Area / Height
Length of base = 55.5 sq in / 15 in
Length of base = 3.7 in
Therefore, the length of the base of the rectangle is 3.7 inches, and the answer is D.
