let x be the money she spent so that she can earn the free t-shirt.
since, she already spent $112.49
⇒![x + 112.49](/tex.php?f=x + 112.49)
also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.
then,
we have an inequality i.,e
![x + 112.49 > 250](/tex.php?f=x + 112.49 > 250)
subtract 112.49 from both sides we get;
![x > 137.51](/tex.php?f=x > 137.51)
therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
