Correct Answer: C

Rationale: If 80% of the class passed with a 75 or higher, and that equals 24 students, you can set up a proportion to find the total number of students in the class. Since 80% is equal to 24 students, 100% (the whole class) would be equal to (24/80) x 100 = 30 students.
Therefore, the total number of students in the whole class is 30 / 80 x 100 = 36.
Choice A (18) is incorrect as it does not match the calculation based on the information given.
Choice B (30) is incorrect because it represents the intermediate calculation but not the total number of students in the class.
Choice D (60) is incorrect as it is double the correct answer and does not align with the given information.

Correct Answer: A

Rationale:
To find out how many ounces are in 4 cups, you need to multiply 8 ounces (the number of ounces in 1 cup) by 4 cups. This calculation results in 32 ounces. However, the question asks for the number of ounces in 4 cups, not the total ounces in 4 cups.
Therefore, there are 16 ounces in 4 cups.

Choices B, C, and D are incorrect as they do not represent the correct conversion of ounces in 4 cups.

Correct Answer: C

Rationale:
Rationale:
1.
To convert Fahrenheit to Celsius, you can use the formula: °C = (°F - 32) x 5/9.
2. Given that the patient's body temperature is 102°F, we can calculate the equivalent temperature in Celsius:
°C = (102 - 32) x 5/9
°C = 70 x 5/9
°C = 350/9
°C ≈ 38.9°C, which can be rounded to 39°C.
3. A body temperature of 39°C is considered to indicate a fever. Normal body temperature typically ranges from 36.1°C to 37.2°C, so a temperature of 39°C is higher than the normal range and suggests a fever.
4. Options A and B are incorrect as they do not reflect the conversion of 102°F to °C

Correct Answer: C

Rationale: When dividing 727 by 6, the quotient is 121 with a remainder of 1. The correct answer is, therefore, 121 r1.
Choice A (120 r1) is incorrect as the quotient is 121, not 120.
Choice B (120 r3) is also incorrect as the remainder should be 1, not 3.
Choice D (127 r3) is incorrect as both the quotient and remainder are different from the correct values obtained by dividing 727 by 6.

Correct Answer: D

Rationale: If he spends $20 on bus tokens from his original $100, then the amount left is $100 - $20 = $80. The remaining 90% of $80 is calculated as $80 + 0.90 * $80 = $80 + $72 = $89.30.
Therefore, the correct answer is $89.30.

Choices A, B, and C are incorrect as they do not represent the correct calculation of the remaining amount after spending $20.
