The problem is: jin donated earning from 2 songs to a charity. he donated $864 altogether. jin's second song earned 5 times as much as his first song. a: how much money did jin's second song earn? show your workb: how much more money did jin's second song earn than his first song? explain.

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 terms
6x = 864, then divide both sides by 6
6x/6 = 864/4
x = 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.
