Which expression is equivalent to 4t + 3t

 C

Step-by-step explanation:

i think

C. 7t

Step-by-step explanation:

What we know:

We are looking for an expression equal to 4t + 3t.

There are 4 choices:

1. 7t²

2. 7 + 2t

3. 7t

4. 12t

The answer does end in t, but is only one term, so B is eliminated.

An exponent is not involved either, so A is also eliminated.

It shows an addition sign, not multiplication, so D is also out.

This leaves C, which is 7t.

Doing this mathematically, add like terms.

4t + 3t

7t

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
