The Bengals begin with a possession on their own 27-yard line. Four plays result in the following: gain of 6, loss of 12, a gain
WARRIOR [948]

Answer:

The final position of the ball is on the 16 yard line.

Step-by-step explanation:

The final position of the ball after the fourth play is given by the initial position, in this case the 27-yard line, followed by a succession of sums and subtractions depending on the outcome of each play. For gains we sum and for losses we subtract. So we have:

final position = 27 + 6 - 12 + 2 -7

final position = 27 - 11

final position = 16

The final position of the ball is on the 16 yard line.
