1. A woman’s dinner bill comes to $48.30. If she adds a 20% tip, which of the following will be her total bill?

• A. $9.66
• B. $38.64
• C. $48.30
• D. $57.96

Correct answer: D

Rationale: To calculate the total bill after adding a 20% tip, you need to find 120% of the original bill. This is because adding a 20% tip means paying 120% of the bill. So, $48.30 × 120/100 = $57.96. Therefore, the correct answer is $57.96. Choice A ($9.66) is incorrect as it represents only the 20% tip amount. Choice B ($38.64) is incorrect as it is the original bill amount without the tip. Choice C ($48.30) is incorrect as it is the original bill amount and does not include the additional 20% tip.

2. Based on the information in the announcement, what might the reader assume about how the university determined the lunch schedule?

• A. The university arranged the schedule based on the department with the most faculty members.
• B. The university checked with the departments to see when the majority of faculty members would be entering the canteen.
• C. The university checked to see when the most faculty members from each department would be entering the canteen.
• D. The university established different times for each department to reduce crowding in the canteen.

Correct answer: C

Rationale: The university determined the lunch schedule by considering when the most faculty members from each department usually enter the canteen. This information is provided in the announcement where it states that the schedules were recommended based on when members of each department should visit the canteen for lunch. Choice A is incorrect because the schedule was not arranged solely based on the department with the most faculty members. Choice B is incorrect as it implies checking with departments about the majority of faculty members entering the canteen, which is not explicitly mentioned. Choice D is incorrect as it simplifies the university's decision-making process, which involved considering the timing of faculty members from different departments entering the canteen.

3. What score must Dwayne get on his next math test to maintain an overall average of at least 90?

• A. 89
• B. 98
• C. 95
• D. 100

Correct answer: B

Rationale: To maintain an overall average of at least 90, Dwayne must aim for a score of 90 on every test. If his current average is below 90, he needs to make up for it by scoring higher on upcoming tests. Choosing 98 ensures that his overall average remains at or above 90. Choice A (89) is below the desired average of 90, so it would not be sufficient. Choices C (95) and D (100) are higher than necessary to maintain an average of at least 90.

4. What is the process of combining two or more substances to form a heterogeneous mixture called?

• A. Dissolving
• B. Diluting
• C. Mixing
• D. Reacting

Correct answer: C

Rationale: The correct answer is 'Mixing.' When substances are combined, a heterogeneous mixture is formed where the components are physically distinguishable. 'Dissolving' (Choice A) is the process of a solute becoming uniformly dispersed in a solvent to form a solution, not a heterogeneous mixture. 'Diluting' (Choice B) refers to reducing the concentration of a solute in a solution. 'Reacting' (Choice D) involves a chemical change where substances interact to form new products, rather than just physically mixing to form a heterogeneous mixture.

5. What is the process of breaking down and rebuilding bone tissue called?

• A. Ossification
• B. Remodeling
• C. Calcification
• D. Osteoporosis

Correct answer: B

Rationale: The correct answer is 'Remodeling.' Remodeling is the process of breaking down and rebuilding bone tissue. Ossification is the process of bone formation, not breaking down and rebuilding bone tissue. Calcification involves the deposition of calcium salts in tissues, but it is not specifically related to breaking down and rebuilding bone tissue. Osteoporosis is a condition characterized by decreased bone density leading to increased bone fragility, not the process of breaking down and rebuilding bone tissue.
