You have an investment account with $300,000 in it all of which is invested in a mutual fund with a beta of 1. You then borrow $100,000 from a bank and add it to your investment account (so you now have $400,000 in the account). If you invest all $400,000 in the account into a mutual fund that has a beta of 1, what is your overall beta? (i.e., you had a beta of 1 before the borrowing, what is it afterwards?)
