Answer:
The answer is 16 ÷ 2 = 8.
Step-by-step explanation:
Now, to find the expression modeled by arrangement of tiles.
So, according to the model in the question.
There are 16 tiles in the model.
So, arrangement of 16 tiles divided into 2 groups.
Where each group consist 8 tiles.
So, we can write as:

As 16 is the number of tiles and 2 is the number of groups.
Now, we can check the expression by doing the division.

Therefore, each group has 8 tiles.

Answer:
$4080
Step-by-step explanation:
We have the amount she will pay back, but first, we need to find the Interest accrued.
Simple Interest is given as:

where P = principal
R = rate
T = time taken (in years)
Therefore, the interest on $3,000 at 9% simple interest for 4 years is:

I = $1080
Therefore, the amount she will pay back is:
$3000 + $1080 = $4080
