Answer:
The total yardage for the four plays is 14
Explanation:
To find the total yardage of the running back, we must add the number of yardage he got in each play. In football, if a player loses yards, he simply is credited with negative yards.
His first carry went for -1 yard. So his total is -1 yard.
In his second carry, he lost 4 yards. So his total is now -1 - 4 = -5 yards
In his third carry, he got 12 yards. So his total is now -5 + 12 = 7 yards
In his fourth carry, he got 7 yards. So his total is 7 + 7 = 14 yards.
