To analyze Bob's financial situation:
- Bob earned $25 from yard work.
- Bob owes his dad $30 for his iPad case.
To find out what is true about Bob's money at the end, we can calculate:

This means Bob still owes $5 after earning the money.

This accurately reflects that Bob's overall financial situation results in him still owing $5 after earning the money.
