Lisa and Daisy work at a hair salon. The salon charges $18 for a hair styling session with Lisa and $12 for a session with Daisy. The income on a certain day is projected to be $216. This situation can be represented by the equation 18x + 12y = 216, where x is the number of Lisa's customers and y is the number of Daisy's customers. How many customers would Lisa need to serve to attain the projected income if Daisy calls in sick that day?

You would want to divide 216 by 18 and by doing that you would get 12.
Since Daisy is sick we won't need the 12y in the equation. That leaves us with 18x = 216 which represents Daisy's work for the day. 

Simply solve for x.
18x = 216 
18x/18 = 216/18
x = 12



So Daisy would need to work with 12 customers in order to reach the average income for a day without Lisa's help.

Check: 18(12) = 216
