To find the revenue received from selling one more item, we need to calculate the revenue for selling 76 items and subtract the revenue for selling 75 items, since we are interested in the change in revenue from one more item sold.

Revenue for selling 75 items: 
R(75) = 11eb0d3b_979c_0c32_9790_07174b47ceef_TB1243_11​(75) = 75(27) = 2,025

Revenue for selling 76 items: 
R(76) = 11eb0d3b_979c_0c32_9790_07174b47ceef_TB1243_11​(76) = 76(27) = 2,052

Therefore, the revenue received from selling one more item is R(76) - R(75) = $2,052 - $2,025 = $27.

The correct answer is D.
