<h3>
Answer:</h3>
y = 0.026x – 0.05
<h3>
Step-by-step explanation:</h3>
When the number of pages increases by 100, the cost goes up 2.60, so the price per page is 0.026, and the cost for x pages is 0.026x.
For the first 50 pages, the cost is only 1.25, which is less than 1.30 by 0.05, so the cost function is ...
... y = 0.026x - 0.05
You used the fact that you can multiply both sides of an equality by the same, non-zero constant.
So, if you start with the trivial equality
you can multiply both sides by 3:

But if
,
becomes
, which is
. So, we have

which leads to

if you recall that
