Given Consumer Income = $60
Price of product A = $8.42
Price of product B = $26.32
The optimal bundle will be the one when MUA/PA = MUB/PB
Q | MUA/PA | MUB/PB |
1 | 2.02 | 0.95 |
2 | 1.66 | 0.91 |
3 | 1.31 | 0.87 |
4 | 0.95 | 0.84 |
5 | 0.59 | 0.80 |
6 | 0.24 | 0.76 |
7 | 0.00 | 0.72 |
8 | 0.00 | 0.68 |
9 | 0.00 | 0.65 |
10 | 0.00 | 0.61 |
If the Consumer buys 4 units of product A and 1 unit of product B,
his total spending will be 4*8.42 + 1*26.32 = 33.68 + 23.32 = $60.
The total utility = 17 + 14 +11 +8 +25 = 75.
Therefore, the optimal bundle is 4 of product A and 1 of product B.
