Consider an Individual who buys films (F) and books (B) with the following utility function: (, ) = 5 + 2 This individual also has the following incomes (m) and prices (pF and pB): = $50, f= $5, B= $10 Given the above: 12. Draw the utility functions for utility levels of 10 and 20. Draw these with films on the x- axis and books on the y-axis. Show your work. 13. What is the MRS for these utility functions? Assume that films remain on the x-axis and books remain on the y-axis. Show your work.

14. What is the consumption bundle that delivers the highest level of utility that is also affordable? Show your work.
