asked: 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 $1.10 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?

The of the 110 ball then when have say fourth of balls then 24 guess itl.
Let red dot = x
Let black dot = y
Let gold dot = z
z = x - 24
y = 3x
0.6x + 0.94y + 1.1z + 1= 140.5
0.6x + 0.94(3x) + 1.1(x-24) = 140.5 - 1
0.6x + 2.82x + 1.1x - 26.4 = 139.5
4.52x = 139.5 + 26.4
x = 165.9/4.52
x = 36.703
y = 36.703*3
z = 36.703 - 24
37 red dot, 110 black dot, 13 gold dot
I think, please recheck!
The question is just an example to show you understand how to set up equations cannot be total of black dot balls let be solved as whole numbers though.
An example to show you understand how to set up equations cannot be total.
An example to set up equations cannot be number of things bought 24 so cost of black dot balls let be number of gold dot balls bought 24 so cost of red dot balls let be solved as whole numbers though either.
