Let's evaluate each statement for its truthfulness.
A. **True** - If a scuba diver is 30 feet below sea level, they must rise 30 feet to return to sea level (where the boat is).
B. **False** - The bank charged $10 to replace the debit card, which is an expense. The use of the card to make a $10 purchase is another transaction, leading to a total net effect of -$20 (the replacement fee plus the purchase).
C. **True** - If the temperature rose 15 degrees and then dropped 15 degrees, the net change is zero degrees (15 - 15 = 0).
D. **False** - The football player's net yardage can be calculated as follows: 12 yards gained - 5 yards lost - 7 yards lost = 0 yards - 7 yards = -7 yards. Therefore, his net yardage is -7 yards, not zero.
Based on this analysis, the true statements are **A** and **C**.
