The best answer to choose here would be D: -18 yards
The person records three plays, simply having results of: +4, -33, and +11. The best way to find out the spot of the ball relative of its starting position is just create an equation:
4 - 33 + 11 = ?
(33 being a negative term brings subtraction, 4 and 11 as positive terms bring addition.)
4 - 33 + 11 = ?
-29 + 11 = ?
-18 = ?
Therefore, the ball was -18 yds from the spot of where it originally started.
