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

Step-by-step explanation:

We know that Chad charges $5.50 per window washed, and he deducts $3.25 from the total cost if the costumer provides the supplies. However, in this case, the costumer doesn't provide the supplies, so Chad will charge $5.50 per window.

This relation can be expressed as

Where represents windows.

If he charges $27.50, the relation is

Therefore, the right answer is the third choice

If you want to find the number of windows Chad washed, you just have to solve the expression

Chad washed 5 windows.
