What is the solution to the equation represented by the model below? x= -14
x= -2
x= 2
x= 14

C

Step-by-step explanation:

On the left, we have 3 positive x bars and 8 1s.

Hence, the left can be represented by the following expression:

On the right, we have 4 positive x bars and 6 1s.

Hence, the right can be represented by the following expression:

The two are equivalent. Therefore:

Solve for x. Subtract 6 from both sides:

Subtract 3x from both sides:

Flip:

Hence, our answer is C.

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
