Since Jin donated his money to charity and he donated $864, that is our total.
We don't know the first amount, so we can call it x.
We don't know the second amount either, but we do know it was 5 times the first, so 5*x = 5x.
We first need to find how much Jin earned for the first song. We need to find x.
x + 5x = 864, then combine like terms6x = 864, then divide both sides by 66x/6 = 864/4x = 144
The fist song made $144. But the second made 5 times that. So we just multiply 144 by 5. 144*5=720.
The final answer is $720.

Answer:
and
Step-by-step explanation:
we know that
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
Equate the function to zero
so
substitute in the formula
Remember that
so
Simplify
therefore
and
62.10 < = (20 + 0.5x) + 0.15(20 + 0.5x)
62.10 < = 20 + 0.5x + 3 + 0.075x
62.10 < = 23 + 0.575x
62.10 - 23 < = 0.575x
39.10 < = 0.575x
39.10/0.575 < = x
68 < = x.......maximum number of pages is 68
