Answer:
$360.
Step-by-step explanation:
First we need to find how much it costs for a single case of printer paper.
48 ÷ 2 = 24
It costs $24 to buy one case of 12 packages.
Now we have to figure out how many cases we will need to buy for the total amount of 180 packages.
I will divide 12 from 180.
180/12 = 15.
You will need to buy 15 cases to get 180 packages.
Now to find the cost, we have to multiply.
x = 15 (amount of cases)
y = $24 (price of case)
z = How much it costs.

Substitute:

Multiply:


If the price does not change, the total cost of next month's order will be $360.

The value of W when V = 9 is 405
<h3>How to solve for W?</h3>
The variation is a direct variation from W to V^2.
This means that:
W = kV^2
Where k is the constant of variation.
W = 320 when V = 8 means that:
320 = k * 8^2
Evaluate
320 = 64k
Divide both sides by 64
k = 5
Substitute k = 5 in W = kV^2
W = 5V^2
When V = 9, we have:
W = 5 * 9^2
Evaluate
W = 405
Hence, the value of W when V = 9 is 405
