a) Ans: In order for Jamal to maximize his utility, 3 cup cakes and 2 cream puffs should he buy.
Explanation:
MU = Change in TU / Change in Q
Utility maximization condition is where ;
Entire given money outlay must be spent on both the goods.
MUcakes / Pcakes = MUcream puffs
/Pcream puffs
Budget constraint;
Y = Pcakes * Qcakes + Pcream puffs * Qcream puffs
$12 = ($3 * 3 ) + ( $1.5 * 2 )
