16. George Wilkins checked the spreadsheet where he keeps track of his assets and liabilities. He discovered that (i) he owes $80,000 on his house, which he believes to be worth $150,000; (ii) his car is worth $20,000, against which there is $2,000 on the remaining bank loan; (iii) his stock portfolio has risen to

$50,000; (iv) he has a $10,000 balance in his bank account, which is earning a 1.2 percent annual interest rate; and (v) the value of his other belongings is

$45,000. He has just received his monthly paycheck for $6,000 and he is trying to decide about taking a vacation and whether or not to pay off his car loan. His monthly expenses are $3,000 which includes the interest expense on his auto loan. He has two possible vacation choices: the Bahamas for $2,000 or a local beach for $1,000. If he has any money left over at the end of the month, it will go into his bank account. If he doesn’t have enough money to cover all of his expenses for the month, he will sell enough of his stock to cover the excess expenses.
