Allied Transistor is a company that makes load/force sensors based on capacitive sensing technology. The company wants to have $30 million for a plant expansion five years from now. If the company currently has a total of $15 million in an investment account set aside for the expansion, how much more must the company add to the account next year (i.e. one year from now) to accumulate the $30 million 5 years from now? The account earns interest at 10% per year.
