Chad washes windows after school to make some extra money. he charges $5.50 to wash each window. if the customer provides the supplies, chad deducts $3.25 from the total cost. one customer paid a total of $27.50 and did not provide supplies. which equation could be used to find the number of windows, w, that chad washed for this customer?

5.5w + 3.25 = 27.5
5.5w - 3.25 = 27.5
5.5w = 27.5
5.5 - 3.25w = 27.5
