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=

We need to solve for x
To get x alone we need to remove the denominator 5
To remove denominator 5 we multiply by 5 on both sides
2x = 50
2x means 2 times x
2 is multiplied with x. so to remove 2 we divide by 2
So x= 25
