Question

4 identical pens cost N dollars how many dollars do K pens cost
assuming N and K are variables

Answer 1

Explanation:

To determine the cost of K pens based on the given information that 4 identical pens cost N dollars, we can set up a proportion.

Let's assume C represents the cost of K pens in dollars. The proportion can be set up as follows:

4 pens / N dollars = K pens / C dollars

Cross-multiplying, we get:

4C = NK

Now, to isolate C and find the cost of K pens, we divide both sides of the equation by 4:

C = NK / 4

Therefore, the cost of K pens would be NK/4 dollars.
