1 yd = 3 ft

y - the number of yards

[tex]y=3\cdot f\to y=3f[/tex]

For this case, we have by definition:

[tex]1 \ yard = 3\ feet[/tex]

We then define the following variables:

  • y: number of yards
  • f: number of feet

We write the function that relates both variables:

[tex]y = 3f[/tex]

Answer:

an expression for the number of yards in f feet is:

[tex]y = 3f[/tex]
