Question 1 of 5
On a floor plan drawn at a scale of 1:100, the area of a rectangular room is 30 cm². What is the actual area of the room?
Correct Answer: D
Rationale: On a 1:100 scale drawing, each centimeter represents one meter. The area of the room in the scale drawing is 30 cm², which means the actual area is 30 m².
Choice A (30,000 cm²) is incorrect as it doesn't account for the scale conversion.
Choice B (300 m²) is incorrect because it multiplies the scale area directly by 10,000, which is not the correct conversion.
Choice C (3,000 m²) is also incorrect as it applies the scale factor incorrectly.

Pernell's scores on her last five chemistry exams were 81, 92, 87, 89, and 94.
Question 2 of 5
What is the median of Pernell's scores (81, 92, 87, 89, and 94)?
Correct Answer: B
Rationale:
To find the median, we first need to arrange the scores in ascending order: 81, 87, 89, 92, 94. Since there are five scores, the middle score would be the third one, which is 89. Hence, the median of Pernell's scores is 89.
Choice A (87) is incorrect because it is the second score in the ordered list, not the middle one.
Choice C (92) and
Choice D (94) are also incorrect as they are not positioned in the middle of the ordered series.

Question 4 of 5
Erma has her eye on two sweaters at her favorite clothing store, but she has been waiting for the store to offer a sale. This week, the store advertises 25% off a second item of equal or lesser value. One sweater is $50, and the other is $44. What will Erma spend?
Correct Answer: C
Rationale: Erma receives a 25% discount on the $44 sweater, which amounts to a $11 discount.
Therefore, she pays $44 - $11 = $33 for this sweater. Adding this discounted price to the $50 sweater, Erma will spend a total of $50 + $33 = $83.
Choice A, $79, is incorrect because it does not include the correct calculation for the discounted sweater.
Choice B, $81, is incorrect as it does not consider the discounts on both sweaters.
Choice D, $85, is incorrect since it overestimates the total amount Erma will spend.
Question 5 of 5
Jerry needs to load four pieces of equipment onto a factory elevator that has a weight limit of 800 pounds. Jerry weighs 200 pounds. What would be the average weight of each item so that the elevator's weight limit is not exceeded?
Correct Answer: B
Rationale:
To find the average weight per item, subtract Jerry's weight from the elevator's weight limit: 800 - 200 = 600 pounds. Since there are 4 items, divide 600 by 4 to determine that each item should weigh 150 pounds.
Choice A (128 pounds), C (175 pounds), and D (180 pounds) are incorrect as they do not correctly calculate the average weight per item to ensure the elevator's weight limit is not exceeded.
