Lila personally bought three insurance policies on her life. She borrowed $$\$28,500$$ and prepaid the first five years' worth of annual payments on a whole life policy. In addition, she borrowed $$\$ 4,200$$ and paid one of the two required premiums on a group term policy through her professional organization. Finally, she borrowed $$\$ 3,000$$ and bought utilities mutual fund shares. The principal and interest of the fund's assets are to be appropriated in a timely fashion by Lila to make payments on a five-premium endowment contract. Interest charges for the three loans were $$\$ 2,500, \$ 420$$, and $$\$ 310$$, respectively. How much of this interest can Lila deduct?
