1) Suppose Jake has $90, which he spends on large fries and ketchup. Price of large fries is $3 and price of a packet of ketchup is $1. Jake also has a coupon entitling him to 20 free large fries. For Jake, Ketchup and fries are complements. Indeed he only enjoys his large fries if he has 2 packets of ketchup with it. Draw Jake’s budget set. Draw a few of his ICs representing his preferences. Find Jake’s optimal bundle, label it A on your graph and write it below. Draw the IC that passes through his optimal bundle. A=( K, F) 0 10 20 30 40 50 60 70 80 90 Ketchup 0 5 10 15 20 25 30 35 40 45 50 Large fries
