A recent college graduate borrows \$150,000 at an interest rate 6% to purchase a condominium.  Anticipating steady salary increases, the buyer expects to make payments at a monthly rate of $800+10t$, where $t$ is the number of months since the loan was made.

Assuming that this payment schedule can be maintained, when will the loan be fully paid?
