The supply of units of a certain product per month is given by the function S(x) = y =  15.75x. 

The demand for these units per month is given by the function

D(x) =y = ,

where   y  =  price of the product in R1 000’s;  x  = number of the product in 100’s,  supplied or sold in a month. Determine the point of equilibrium algebraically.
