Step 3: Subtract 14 from both sides.

Step 4: Divide both sides by -18.

let x be the money she spent so that she can earn the free t-shirt.

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
