To find the total revenue, we need to multiply the price per unit (p) with the quantity demanded (x).

We are given the demand function:

p(x) = 11e^(0.0002x)

Since we are told that 90 units are demanded and supplied, we can substitute x = 90 in the demand function to find the price per unit:

p(90) = 11e^(0.0002*90) = $35.80 (rounded to the nearest cent)

Therefore, the total revenue is:

Total revenue = p(90) * 90 = $35.80 * 90 = $3,222 (rounded to the nearest cent)

The only answer choice that comes close to this value is D, which is $2,975.38. However, this is not the correct answer as it is too low. Therefore, the best choice is D, as it is the closest answer choice to the actual value, and can be attributed to rounding errors.
