Step-by-step explanation:
Lin Chow recorded yardage gained and yardage lost as integers while watching a football game. To determine the net gain or loss, you simply add the numbers together. The yardage gained was 14 and 9, and the yardage lost was -7.
Therefore, the calculation is as follows:
14 (gained) + (-7) (lost) + 9 (gained) = 14 - 7 + 9 = 7 + 9 = 16
Lin had a net gain of 16 yards.
The correct answer is a) Net gain of 16 yards.
