3. (15 points) \\Robert derives utility from consuming Hersey bars (h) and Twix bars (t) according to the utility function: u(h, t) = 2h + t a Draw Robert's indifference map over Hersey and Twix bars, and illustrate his utility maximizing choice of the two products. b. Find Robert's Marshallian demand for Hersey and Twix bars as a function of Income (Y), the price of Hersey bars (px), and the price of Twix bars (p,). Be sure to indicate the conditions where there is a corner solution or not. In doing so consider when the ratio of prices is greater than, less than, or equal to the ratio of marginal utilities for each good. Hint: Y=Pwh+Pit. You also know the ratio of prices between Ph and Pt
