A manufacturer has determined that when x thousand units of a particular commodity are produced, the price at which all the units can be sold is p = F (x) dollars per unit, where F is
the demand function
F (x) = 10 −xe^(0.02x)
a) At what price are 5000 (x0 = 5) units demanded?
b) Find the consumers’ surplus when 5000 units are demanded!
I really do not get how to solve this. Thank you so much!
