Answer:
Model B
Step-by-step explanation:
Model B correctly displays sienna's and jacob's equations.
For sienna, the $8 can be represented as 8 unit blocks, which is displayed in model 2. The $3 per week can be represented as 3 x tiles, as shown in the picture, because it represents how many weeks.
For jacob, the model shows 6 unit blocks which represents his 6 dollars. The $4 per week is represented with the 4 x tiles, and we use x tiles because we are calculating how many weeks.
The exponential function that approximates the amount of money in her account using a weekly growth rate is:
<h3 />
What is an exponential function?
An increasing exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the growth rate, as a decimal
In this problem, the yearly function is:

Considering that a year has 52 weeks, we have that:
0.06/52 = 0.001154
Hence:

I'm assuming you mean a compression of factor 6
In that case, it will be h = 1/6x
Do you know how to add fractions? let me know if u dont
