Select all the equations where x = 3 is a solution. X-3 = 0
O 1 + x = 2
9 - x= 3
o 6=22
3
O x2 = 9

X-3 = 0 x = 3 is a solution.

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

since, she already spent $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

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
