dimmsdale discount golf supply sells titleist golf balls for 60c each, the nike golf balls for 94c each and the Calloway golf balls for 1.10 each. A golf pro bought two dozen more titleist golf balls than calloway golf balls and three times as many nike golf balls as titleist golf balls. if the golf balls and one dollar's worth of tees cost140.50, how many golf balls of each kind were bought?

I can show you how to this one, if you're still interested. It might be better as a private session, so I can upload pics/screenshots.

We need to use algebra. Let us say the number of Calloway ones, is b. Then, if he buys 2 dozen more Titleist ones, he buys 24 x b of the, or 24b. Now if he buys 3 times as many Nike ones as Titleist ones, he buys 3 x 24b = 72b

Although reading it again, I think what it means when it says 2 dozen more, is simply 24 more Titleist than Calloway, which would make it (b +24). That's what I get for trying to doing maths too early on a Sunday morning!!!!! So, in fact we get; 0.60b + 0.94(b+24) + 1.10( 3(b+24) + 1 = 140.50 Then, multiply out the equation and solve. Hope this helps.
