Let's analyze the situation step-by-step for Bob:
- Bob earned $25 from his yard work.
- Bob owes his dad $30 for his iPad case.
To find out how much money Bob has after accounting for what he owes, we can perform the following calculation:
- Start with the amount Bob earned: +$25
- Subtract the amount Bob owes: -$30
The calculation will be:
25 - 30 = -5
This means that Bob has -$5, which indicates he still owes $5 even after earning $25.
Based on this reasoning, the correct response would be:
Rational answer: Bob still owes money in the end: -30 + 25 = -$5
