Best answer 1 votes 1 votes Let the initial price be 'P' and initial sales be 'S' So, the initial revenue C = P*S Now, Pnew = 1.3P and Snew = 0.8S $\therefore$ Cnew = Pnew*Snew = 1.3P*0.8S = 1.04C So, there is a 4% increase in total revenue. C is the answer. just_bhavana answered Sep 27, 2017 • selected Sep 27, 2017 by Arjun just_bhavana 1.5k points comment Share See all 0 reply Please log in or register to add a comment.
