=+f. Using your answers so far, determine R—the least I am willing to accept to give up my coupon. Then determine P—the most you are willing to pay to get a coupon. (Hint: Use your graphs from A

(a) to determine the appropriate values to plug into the expenditure function to determine how much income I would have to have to give up my coupon. Once you have done this, you can subtract my actual income I 5 100 to determine how much you have to give me to be willing to let go of the coupon. Then do the analogous to determine how much you’d be willing to pay, this time using your graph from A(b).)
