Question

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

Answer 1

5.5w - 3.25 = 27.5 I hope this helps

Answer 2

5.5w=27.5
The reason is because this customer is not providing supplies so they do not need to subtract 3.25.
