Answer:

[tex]\sf D) \quad s=8 \frac{1}{4}t[/tex]

Step-by-step explanation:

  • t  = time (in hours) → this is the independent variable
  • s = total area cleaned (in square feet) → this is the dependent variable (as the number of square feet cleaned depends on the number of hours worked)

Therefore, if the rate of cleaning is 8 1/4 square feet per hour, the relationship between s and t is:

[tex]\sf s=8 \frac{1}{4}t[/tex]
