4(8+1); Peter is adding one marker to each box so we add 1 to 8 first because of order of operations (PEMDAS). There are 9 markers in each of the four boxes, 9 x 4 is 36 markers total
Question 1:
For this case we have an equation of the form:

Where,
- <em>k: inverse variation constant.
</em>
Then, substituting values we have:

From here, we clear the value of k.
We have then:

Answer:
the constant of inverse variation is:

Question 2:
For this case we have:

Where,
- <em>k: constant of variation.
</em>
Then, substituting the value of the constant we have:

We now substitute the value of x:

Answer:
the value of y when x = 4 is:

First you divide 17.5/ 3 and then the answer multiply by 15 and get 87.5 i think
I’m pretty sure it is B but i’m not positive.
Since you didn’t specify that it needed to be y as a function of x, all of the above equalities can be rewritten as functions. However, in case that you meant to imply that, A and B are both not valid for y as a simple function of x.
