Correct Answer: B

Rationale: To convert 8 pounds and 8 ounces to kilograms, first convert pounds to kilograms (1 lb = 0.453592 kg) and ounces to kilograms (1 oz = 0.0283495 kg). So, 8 lbs + 8 oz is approximately 3.9 kg. Therefore, choice B (3.9 kilograms) is the correct equivalent. Choice A (3.6 kg) is too low, and choices C (17.6 kg) and D (18.7 kg) are too high based on the conversion rates.

Correct Answer: D

Rationale: The total bill includes the original cost of dinner and the tip. To find the tip amount, we calculate 20% of $48.30, which is $9.66. Adding this to the original bill gives $48.30 + $9.66 = $57.96. Therefore, the correct answer is D. Option A is incorrect as it only represents the tip amount. Option B is incorrect as it is the original bill amount without the tip. Option C is incorrect as it is the same as the original bill without the tip.

Correct Answer: A

Rationale: To calculate the shop's revenue over three days, we need to consider the total sales of sandwiches, drinks, and cookies over the three days. The revenue formula should include the earnings from each item multiplied by the quantity sold. Therefore, the correct equation is r = 4s + 2d + 1c. This is because for each sandwich sold, the shop earns $4, for each drink $2, and for each cookie $1. Choices B, C, and D are incorrect as they incorrectly multiply the earnings by multiples of the quantities sold, which would result in an inflated revenue amount.
