What you will want to do is replace x with the amount of customers so it would be 42 squared divided by 3025-55x42 which should hopefully give you your answer which is 2.339 but you may have to round it as you can’t have 1/3 of a person etc hope this helps, let me know if I’m wrong
Emily = x
Samantha = x + 2
Lauren = x + 4
x + (x + 2) + (x + 4) = 42
x = 12
Thus:
Emily = 12
Samantha = 14
Lauren = 16
