Alice is a salesperson in a jewelry store and earns $110 per week, plus 15% of her weekly sales. If Alice makes $485 in one week, what are her sales for that week?
Let X be Alice's sales for that week.
Alice earns 15/100*X = X/6.67 because 15/100 = 1/6.67.
Alice's total earnings are 110+X/6.67 = $<<110+X/6.67=485>>485.
Thus, X/6.67 = 485-110 = $<<485-110=375>>375.
Therefore, Alice's sales for that week are X = $375*6.67 = $<<375*6.67=2501.25>>2501.25. Answer: \boxed{2501.25}.
