Ineed to solve for x, i need really badly.

x = 40

Step-by-step explanation:

2x + x + x + 20 = 180

4x + 20 = 180

-20 -20

4x = 160

/4 /4

x = 40

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
