Bank B provides explain your decision theoretical. consistent conclusion.) Your firm keeps generating $5,000 cash per quarter from the operation, and you deposit all the cash into your savings account. One year later, your Research & Development department comes up with a cutting-edge technology. Based upon this tech, you can release a new product, uPhone Max. You need to upgrade your equipment in order to produce uPhone Max. The estimated cost to upgrade is $40,000. You need to raise up the fund for the upgrade.
