Ответ:
This is the correct equation because:
x represents the clients that got a cut (at a cost of 35)
So the total profit she earned from just the cuts is 35 times the number of people for a cut
y represents the clients that got a cut and color (120)
So the total profit she earned from the cut/color is 120 times the # of people for cut/color
It is equal to $500 because thats how much Earyn earned!
I hope this helped
