Barry has a bank account with a balance of $50.00. Barry owes $32.00 to his credit card
company and he owes $20.00 for a yearbook. What would Barry’s bank balance be, if both
debits were paid?
Explanation:
Negative account balances signify debt. Debt is money that you owe or the amount of money
that needs to be paid to achieve an even or zero balance.
Barry has a bank account balance of $50. He has to pay $32.00 for his credit card and $20.00
for a yearbook So his total expenses = $32.00 + $20.00
= $52 He has a balance of $50 and he has to pay $52.
So the balance of his account after paying all expenses = $50 - $52 = -$2 He has a negative
account balance of -$ 2.

Dave and Nick are friends from college. Since graduation, they have both gained several
pounds, and now weigh exactly the same. At New Year's, they decide to start tracking their
weight. Each week, they record their weight in a computer program, and it tells them where they
are relative to their initial weight. After 8 weeks, Dave's computer reads "-6" and Nick's reads "8." Write an inequality to compare these numbers. Explain the inequality in the context of the
situation. Now, take the absolute value of each number and compare them. Explain what the
absolute value comparison means in the context of the problem.
4. The Nurse Problem - The new nurse on the fourth floor of the hospital had a really, really,
busy, busy day. First it was the patient in the middle room of that floor, who wanted somebody
to look at a red spot on her big toe, which was in a cast.
Then the patient 3 rooms farther down at the east end of the hall rang and complained that his
lunch hadn't been delivered. Sure enough, he was right! So the nurse had to go to the pantry,
which was 5 rooms back to the west, to arrange for another lunch.
5. Robinson’s hotel room rent is $80. His food bill is $30 and the taxi costs
