Correct Answer: A

Rationale: To find the total days off work, we add Bill's remaining vacation days (5.5) and sick days (3.25). 5.5 + 3.25 = 8.75 Therefore, Bill will have 8.75 days off work if he uses all of his remaining vacation and sick days. Choice A (8.75) is correct because it accurately represents the total days off. Choices B, C, and D are incorrect as they do not correctly calculate the total days off based on the given information.

Correct Answer: C

Rationale: To find the number of customers served, we add the incidents that delayed the server's service time: 43 customers + 2 broken glasses + 5 slips = 50 incidents Given that the server breaks 10 glasses the next day, we double the incidents: 50 incidents x 2 = 100 incidents Each incident corresponds to serving a customer, so the server served 100 customers in total. Thus, the correct answer is C (86 customers). Choices A, B, and D are incorrect because they do not account for the additional incidents affecting the service time.

Correct Answer: A

Rationale: To find the result of 0.003 x 4.23, you multiply the numbers: 0.003 x 4.23 = 0.01269. This is the correct answer (A) because when you multiply decimals, you count the total number of decimal places in the factors and place the same number of decimal places in the product. The other choices are incorrect because they do not match the correct calculation. Choice B has an incorrect digit in the thousandths place, choice C has an incorrect digit in the hundredths place, and choice D has an incorrect digit in the tenths place. Therefore, the correct answer is A, 0.01269.

Correct Answer: B

Rationale: To find the percentage of band members who missed practice, we need to calculate the ratio of band members who missed practice to the total band members. 9 out of 75 band members missed practice, so the ratio is 9/75 = 0.12 or 12%. Therefore, the correct answer is B (12%). Choice A (10%) is incorrect as 9 out of 75 is not equivalent to 10%. Choice C (15%) is incorrect as 9 out of 75 is not equivalent to 15%. Choice D (18%) is incorrect as 9 out of 75 is not equivalent to 18%.
