Hey guys, could use some insight here...

So this is a basic story problem:

"I paid $22.30 for 6 new golf balls and 10 used balls. If each new ball costs$.65 more than a used ball,how much did I pay for each type of ball?"

I assumed it was as simple as:

10x+6(x+.65)=22.30

But that is apparently incorrect...

I'm banging my head against a wall... maybe the fact that I've been studying for an hour or two straight doesn't help as its psyching me out,but I feel like this is much more difficult then it should be...

My mind is blank right now,what am I missing?

Why do you say it is incorrect? It looks to me like the correct equation to give the price of a used ball.

Holy smokey.

Man I need to learn how to take breaks in between studying...

I re-did my equation and came up with the correct answer...

Thanks anyway,haha.

Are you saying the equation you posted originally is NOT correct? If not, why not?

No, the equation was correct,as I assumed,but my mind was so fried from studying I forgot to multiply .65 by 6 when distributing...

Ah well,thanks again
