To analyze Bob's financial situation, we start with the fact that he owes his dad $30 and earns $25 from yard work.
Here’s the calculation:
- Bob starts with a debt of -$30 (the amount he owes).
- After earning $25, we perform the calculation: -30 + 25 = -$5.
This means that after earning the $25, Bob still owes his dad $5. Therefore, the rational answer that matches the scenario is:
Rational answer: Bob still owes money in the end: -30 + 25 = -$5
