Answer:

He needs to gain more than 26 yards in order to break his record

Step-by-step explanation:

Let y stand for the number of yards he’ll have to gain. The sum of y plus the number of yards he already has (203) must be greater than 229 in order for him to break the record.  

203 + y > 229                           Set up the inequality.

203 − 203 + y > 229 − 203       Subtract 203 from both sides of the inequality.

y > 26
