In an effort to have enough money to finance his

passion for top$-$level off$-$road racing, a mechanical

engineering graduate decided to sell some of his

"toys." At time $t=0,$ he sold his chopper motor$-$

cycle for $$18,000.$ Six months later, he sold his

Baja pre$-$runner SUV for $$26,000.$ At the end of

year $1,$ he got $$42,000$ for his pro$-$light race truck.

If he invested all of the money in a high$-$risk com$-$

modity hedge fund that earned $24\%$ per year com$-$

pounded semiannually, how much did he have in

the account at the end of $2$ years?
