An investor currently holds the following portfolio:

$8,000$ shares of Stock A$,$ worth $$17,000$; Beta $=1\mathrm{.}1$

$15,000$ shares of Stock B$,$ worth $$47,000$; Beta $=1\mathrm{.}9$

$25,000$ shares of Stock C$,$ worth $$97,000$; Beta $=2\mathrm{.}3$

The investor is worried that the beta of his portfolio is too high, so he wants to sell some stock C and add stock D$,$ which has a beta of $1\mathrm{.}0,$ to his portfolio.

If the investor wants his portfolio to have a beta of $1\mathrm{.}70,$ he must replace $ $000$ stock C with stock D$.$
