Brian consumes only two goods, Chocolates and porcelaine lupines. Let X be the number of chocolates Brian consumes and Y be the number of porcelain lupines. Brian's utility function is given by U=20X^2 Y. Suppose initially that the price of chocolates is $1 as is the price of porcelain lupines. Brian's income is $840. Now suppose the price of chocolates rises to $3. Calculate CV and EV associated with the price change
