Final answer:
The price per unit at which the quantity demanded equals 8 units is approximately $54.57.
Step-by-step explanation:
To find the price per unit at which the quantity demanded equals 8 units, we can substitute Qd = 8 into the demand function p = 100e^(-q/2):
p = 100e^(-8/2)
p = 100e^(-4)
p ≈ 54.57
So, the price per unit will be approximately $54.57.
