You have three choices; open 4 new branches, open 10 new branches or open 50 new branches. These choices are based on the fund available to you. As a bank manager, you would like to make as much profit for your bank. You have an estimation of the profit you can make from number of new users as shown in the payoff table below.

Four new branches	$100	$100	$100
Ten new branches	$70	$130	$130
Fifty new branches	$-40	$60	$200

Note: Payoffs are in thousand.

Above is the payoff table that you will use to choose the best alternative based on

1. Maximin criterion

2. Maximax criterion
