To analyze Bob's situation:
- Bob owed Jim $7. This is a negative amount for Bob, represented as -7.
- Bob earned $25. This is a positive amount, represented as +25.
- To find out how much money Bob has after paying off his debt, we calculate:
\(-7 + 25 = 18\).
This means Bob has $18 left after settling his debt.
Based on the options provided:
- Rational/Integer answer: This option states that Bob has some $ in his pocket in the end: -7 + 25 = 18. This option correctly represents the scenario as Bob ends up with $18.
The other options either miscalculate or incorrectly describe Bob's financial situation.
So, the correct choice is: • Rational/Integer answer: Bob has some $ in his pocket in the end: -7 + 25 = 18.
