Please help me set up the equations!!!! I have a lot of trouble with “let” statements and things like that

A store sells the Red Dot golf balls for 60 cents each, the Black Dot balls for 94 cents each and the Gold Dot ball for .10 each. A golf pro bought two dozen more Red Dot than Gold DOt balls and three times as many Black Dot as Red Dot balls. If the golf balls and one dollar’s worth of tees cost 140.50, how many gold balls of each kind were bought?

I am searching for new golf clubs without getting fitted by a golf pro.
Is it worth buying a good set now or settle for a cheap set
worth only 0.00?
The reason for not wanting to get fitted by a golf pro is, all the recommendation’s he may offer I don’t need to spend on.
