Answer: 58 1/3 yards
Explanation:
From the question, we are informed that a football team has a net yardage of −28 1/3 yards on a series of plays and that the team needs a net yardage of 30 yards to get a first down.
The number of yards that they have to get on their next play to get a first down would be calculated as:
= 30 - -28 1/3
Note that minus × minus = plus
= 30 + 28 1/3
= 58 1/3 yards
