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

3.25w=27.5 is the correct answer.

Answer:

\(\$5.50w=\$27.50\)

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

@@MATH_TOKEN_1@@

Where @@MATH_TOKEN_2@@ represents windows.

If he charges $27.50, the relation is

\(\$5.50w=\$27.50\)

Therefore, the right answer is the third choice \(\$5.50w=\$27.50\)

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

\(\$5.50w=\$27.50\\w=\frac{\$27.50}{\$5.50}\\ w=5\)

Chad washed 5 windows.
