ΔKLJ and ΔNPM are similar (Angle-Angle). Therefore the sides are in proportion:
We have:
MP = 4x - 4
JL = 20
MN = 30
JK = 25
Substitute:
<em>cross multiply</em>
<em>use distributive property</em>
<em>add 100 to both sides</em>
<em>divide both sides by 100</em>

A company is selling books. It has to pay $500 to start printing the books, and once they have done that, the books sell at $14.99 each. How many books must they sell to make a profit?
First we would model an equation. X will be the amount of books sold, and Y will be profits (in dollars obv). They had to pay $500 before they could start selling, so we must account for that too.
This equation would be
because for every book sold, X increases by 1, increasing Y by 14.99
The answer would be 34 books sold in order to turn a profit. (500/14.99=
