Consumption generates MB of $1.89, 1.51, 1.28, 1.19 & 1.11 from the 1st, 2nd.... dollar allocated to consumption, respectively. If the current interest rate in the market is 31%, then to maximize the total payoff from C and S, it is optimal for the household to choose C = and S- C=1;S=4 OC 2: S-3 C-3:S-2 OC-4S-1
