50 cent = 0.5 dollar
According to question,
x is the number of 50¢=$0.5 price increases.
b(x) is the revenue generated
He currently charges $3 per book.
i.e. price of book = 3+0.5x
Quantity or average = 38 per day

We can add 10 to both sides to get .
We can subtract from both sides to get
.
Lastly, we divide both sides by 20 to get .
So, and we're done!
