To determine the lowest bank balance, we will compare the given values:
- $123.49
- $75.23
- −$123.69
- $75.89
- −$123.43
The negative values (−$123.69 and −$123.43) indicate that these balances are deficits. To determine which is the lowest, we can look at the negative balances more closely:
- −$123.69 is lower than −$123.43 since −$123.69 is further away from zero.
Comparing all the values, we find that the lowest balance is:
−$123.69
So, the answer in dollars is −$123.69.
