Answer: Choice A
36.6
====================================
Work Shown:
f(x) = 3x
f(12.2) = 3*12.2
f(12.2) = 36.6
x is the length in yards, and f(x) is the length in feet.
12.2 yards = 36.6 feet
To convert from yards to feet, we multiply by 3. That explains how
- 1 yard = 3 feet
- 2 yards = 6 feet
as shown in the screenshot.
