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.

3000 times 2 = 6000
6000 times 2 = 12000
12000 times 2 = 24000
24000 times 2 = 48000

All you have to do is subtract 85 from 510 till you have 0
<span>Z + 1/z = 2
Multiply 1 by both sides
z+z=2
Add z and z together
2z=2
Divide both sides by 2
Final Answer: z= 1</span>
