The demand function for a certain commodity is approximated by: p = 100eq/2where "q" is the number of units demanded at a price of "p" dollars per unit. If there is no demand for the product, what will its price be(in dollars)?

if q is the number of units demanded, and there is no demand > q = 0
so p = 100 e^0 = 100(1) = 100 
The supply of a certain item is y = 3x + 8, where "x" is the number of days elapsed. If the demand is
given by y = 4x, in how many days will the supply equal the demand?
