If x is the cost of the masseuse and massage oils, and she is charging 20% more than that, then what she's really charging is 1.2x. And since she wants that to equal $400, you can write the equation:
1.2x = 400
Divide by 1.2 on both sides to get
x = $333.33
So, the massage oils combined with the cost of the masseuse should not equal more than $333.33
