Math Problem Statement
. It is known that the number of concert tickets demanded is 150 when the price is €40 and 100 when the price is €60. (a)Determine the equation of the demand function in the form Q = f(P) and plot the graph of the function. (b)Use the equation to calculate the change in demand when the price (i) increases by €10, (ii) decreases by €8.
