Betty Bower, an adult, asked Jeff Geetus to lend her $1,000. Geetus replied that he would do so only if Bower's father, Cash, would guarantee the loan. At Bower's request, Cash mailed a signed letter to Geetus: "If you lend $1,000 to my daughter, I will repay it if she doesn't." On September 15, Geetus, having read Cash's letter, lent $1,000 to Bower, which Bower agreed to repay in installments of $100 plus accrued interest on the last day of each month beginning October 31. Cash died on September 16. Later that same day, unaware of Cash's death, Geetus mailed a letter to Cash advising that he had made the $1,000 loan to Bower on September 15. Bower did not pay the installments due on October 31, November 30, or December 31, and has informed Geetus that she will be unable to make repayments in the foreseeable future. On January 15, Geetus is entitled to a judgment against Bower for which of the following amounts? 
Nothing, because if he sues before the entire amount is due, he will be splitting his cause of action.  $300 plus the accrued interest, because Bower's breach is only a partial breach.  $1,000 plus the accrued interest, because Bower's unexcused failure to pay three installments is a material breach.  $1,000 plus the accrued interest, because the failure to pay her debts as they come due indicates that Bower is insolvent and Geetus is thereby entitled to accelerate payment of the debt.
