For #1-2, model each expression. Then simplify the expression. Expression Model Simplified 1. 3(2x + 1) 2. 2(3x – 2) In #3-4, simplify the expression. Models are optional. 3. 4(x + 1) 4. –2(x + 3)

see below

Step-by-step explanation:

1.  3(2x + 1)

Distribute

3 * 2x +3*1

6x+3

2. 2(3x – 2)

Distribute

2 * 3x - 2 *2

6x -4

3.  4(x + 1)

Distribute

4*x +4*1

4x+4

4.  –2(x + 3)

Distribute

-2*x -2*3

-2x-6

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

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
