Question

level 6, module 3, module assessment 1
a bank account has a balance of -150 dollars.
part a
explain what the number -150 means in this situation.
part b
explain what |-150| means in this situation.

Explanation:

Part A:

In banking, a negative balance indicates the account holder owes money to the bank. A value of -150 dollars means the account is overdrawn by 150 dollars.

Part B:

The absolute value $|-150|$ represents the distance of -150 from 0 on the number line, so it equals 150. In this banking situation, it means the magnitude of the overdrawn amount, or the total money needed to bring the account balance to 0.

Answer:

1. Part A: The number -150 means the bank account is overdrawn by 150 dollars; the account holder owes the bank $150.
2. Part B: $|-150|$ equals 150, and in this situation, it means the total amount of money (150 dollars) required to pay off the overdraft and bring the account balance to $0.
