Assume that the function for the demand for flour is given by: Qd = f(Y, Pc, Ps) = 0.05Y + 10Pc - 5P Where la is the demand for flour, Y is income, Pp is the price of flour and Pc is the price of coconut flour. a) Apply total differential to find the approximate change in the demand of flour with a 1% increase in income, initially, Y=10,000, P= = 5 and Pc = 7. b) Apply total differential to find the approximate change in the demand of flour with an increase in income of $1 initially, Y=10,000, P= = 5 and Pc = 7. c) Apply total differential to find the approximate change in the demand of flour with a 1% increase in the price of flour, initially, Y=10,000, P= = 5 and Pc = 7. d) Apply total differential to find the approximate change in the demand of flour with a $1 increase in price of flour, initially, Y=10,000. Pp = 5 and Pc = 7
