Mr. Akhter is a businessman. He has just opened a gift store in a busy city area. He purchases all the goods at a wholesale price, but he wants to make the retail price 16.5% higher than the wholesale price. He also has to account for 8.75% sales tax on the retail price before displaying the final price tag on the gift item. If Mr. Akhter sells a cute Barbie doll to a customer for $19.95, which of the following price could be wholesale price of Barbie doll?

(A) $9.13
(B) $10.35
(C) $14.25
(D) $15.75

To find the wholesale price of the Barbie doll, we need to work backwards.

First, we need to remove the sales tax of 8.75% from the retail price of $19.95.

$19.95 - (8.75% * $19.95) = $19.95 - $1.74 = $18.21

Now, we need to calculate what the wholesale price would be, which is 16.5% less than the retail price.

$18.21 / (1 + 16.5%) = $18.21 / 1.165 = $15.63

Among the answer choices, the closest value to $15.63 is (D) $15.75. Therefore, D is the best answer.

To determine the correct answer, let's analyze each option:

1. General John Burgoyne: He was a British general who fought against General Washington during the American Revolutionary War. He did not assist General Washington in training the army at Valley Forge.

2. General Barry St. Leger: He was another British general who participated in the American Revolutionary War, but he was not involved in training the army at Valley Forge.

3. General Baron von Steuben: He was a Prussian military officer who played a crucial role in training and disciplining the Continental Army at Valley Forge. He implemented strict training methods and standardized procedures that helped improve the army's effectiveness. General von Steuben's contributions were significant, making him the best answer choice.

4. General Benedict Arnold: Initially, Benedict Arnold fought for the Continental Army and played a pivotal role in some victories. However, he later turned traitor and joined the British side. Therefore, he did not assist General Washington in training the army at Valley Forge.

Based on the analysis, the correct answer is General Baron von Steuben.
