Chad washes windows after school to make some extra money. He charges $5.50 to wash each window. If the customer provides the su
pplies, 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? 5.5 w = 27.5
5.5 w + 3.25 = 27.5
5.5 - 3.25 w = 27.5
5.5 w - 3.25 = 27.5
