Correct Answer: B

Rationale: To calculate the interest earned on a principal of $1,000 with a 5% annual interest rate, you multiply the principal by the interest rate: $1,000 x 0.05 = $50. Therefore, the correct answer is B, $50. Choice A is incorrect as it miscalculates the interest. Choice C overestimates the interest earned. Choice D is close, but $55 is not the correct calculation based on the given information.

Correct Answer: A

Rationale: To calculate the annual dividend Mr. Rogers receives for his 400 shares, we need to find the dividend per share first. For Mr. Parker, the dividend per share is $180/150 = $1.20. So, for Mr. Rogers, with 400 shares, his annual dividend would be 400 x $1.20 = $480. Therefore, the correct answer is A: $480. Summary: - B: $500 is incorrect because it is not the correct calculation based on the given information. - C: $450 is incorrect as it is not the correct calculation based on the given information. - D: $72,000 is incorrect as it is an excessively high amount and not a reasonable dividend for owning 400 shares.

Correct Answer: A

Rationale: To calculate the distance traveled, multiply the speed (60 mph) by the time (2.5 hours): 60 mph * 2.5 hours = 150 miles. Therefore, the correct answer is B. Choice A (120 miles) is incorrect as it is lower than the correct calculation. Choices C (180 miles) and D (170 miles) are incorrect as they are higher than the actual distance traveled.

Correct Answer: A

Rationale: To calculate Farmer Juan's profit, multiply the total number of eggs (14 acres * 17460 eggs/acre) by the profit per egg ($1.65). 14 acres * 17460 eggs/acre * $1.65 = $403,326. This is the correct answer as it calculates the total profit based on the given information. Choices B, C, and D are incorrect as they do not correctly calculate the total profit using the number of acres, yield per acre, and profit per egg provided in the question.

Correct Answer: C

Rationale: To find the perimeter of a square, we add up all four sides. Since the garden bed has a side length of 8 meters, each side is 8m. Therefore, the perimeter = 8m + 8m + 8m + 8m = 32m (Choice C). Choices A, B, and D are incorrect because they do not correctly calculate the total length of all four sides of the square.
