Earyn owns french twist hair salon. she charges $35 for a cut an $120 for a cut and color combo. yesterday she had seven clients and earned $500. let x represent only the clients that got a cut and y represent the clients that got a cut and color combo.
which of the following equations could be used to represent this situation.
y=7-x
x + y= 500
120x + 35y= 500
(35+120) (x + y)= 500
35x + 120y= 500

The answer for this would be 35x + 120y = 500. The reason behind this is because we want to know how many clients Earyn had that availed of the haircut and the cut and color combo that would lead to a total sales of 500. So if x would correspond to the number of clients that got a haircut and y would correspond to the people that got a combo, then the variables should go with the respective changes. So in this case, it will be 35x to know how much Earyn got in total for the cut and 120y for the combo. Thus 35x+120y= 500
