Correct Answer: A

Rationale:
To find out how many copies each person made, divide the total number of copies made (3,475) by the number of people who used the copier (6). This gives 579 copies per person (3,475 · 6 = 579).
Therefore, each person made 579 copies.

Choices B, C, and D are incorrect as they do not result from the correct division of the total number of copies by the number of people who used the copier.

Correct Answer: A

Rationale:
To solve the expression, we follow the order of operations (PEMDAS). First, we divide 24 by 2 to get 12.
Then, we multiply 8 by 12, which equals 96. Finally, we subtract 96 from 2: 2 - 96 = -94.
Therefore, the correct answer is A, '-94'.

Choices B, C, and D are incorrect as they do not follow the correct order of operations or make errors during calculation.

Correct Answer: C

Rationale:
Rationale:
- Since a stop sign has five equal sides, each measuring 25cm, the perimeter can be calculated by adding up the lengths of all five sides.
- Perimeter = 25cm + 25cm + 25cm + 25cm + 25cm = 125cm
-
Therefore, the perimeter of the stop sign is 125cm.

Correct Answer: A

Rationale:
To find x, we set up the proportion 15:x = 3:8. Cross multiply to get 15*8 = 3*x, which simplifies to 120 = 3x. Dividing by 3 on both sides gives x = 40.
Therefore, x=40 is the correct answer.

Choices B, C, and D are incorrect because they do not match the correct calculation. Option B results from incorrectly dividing 15 by 3 instead of multiplying it by 8. Option C comes from dividing 15 by 3, and Option D is the result of dividing 15 by 8 instead of multiplying by 3.

Correct Answer: D

Rationale:
To convert 1.25 to a percentage, multiply by 100.
Therefore, 1.25 equals 125%. The correct answer is D because 125% is the percentage that represents 1.25.

Choices A, B, and C are incorrect. A (1250%) is 10 times greater than the correct answer, B (25%) is 100 times smaller, and C (50%) is 2 times smaller than the correct percentage equivalent of 1.25.
