Question

Xavier owns and operates Stain-B-Gone Carpet Cleaners. He uses a special non-toxic cleaning solution to clean carpets. There is a proportional relationship between the amount of cleaning solution (in quarts) Xavier uses, x, and the area of carpet (in square yards) he cleans with the solution, y. The equation that models this relationship is y=4x. How many square yards of carpet does Xavier clean with 4 quarts of cleaning solution? Write your answer as a whole number or decimal. square yards

Answer 1

By using the given equation y=4x and substituting x with 4, we calculate that Xavier can clean 16 square yards of carpet with 4 quarts of cleaning solution.

Step-by-step explanation:

The student is asking about a proportional relationship defined by the equation y=4x, where x represents the amount of cleaning solution in quarts, and y represents the area of carpet cleaned in square yards.

To find out how many square yards of carpet Xavier cleans with 4 quarts of cleaning solution, we simply substitute 4 for x in the equation and solve for y.

y = 4 × x

y = 4 × 4 = 16

Therefore, with 4 quarts of cleaning solution, Xavier can clean 16 square yards of carpet.
