How many golf balls of each kind were bought?
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?
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!
