To find a shoe size, the manufacturer uses the equation

S=3f-22
,
where S represents the shoe size and f represents the heel-to-toe length of the foot, in inches. Which of the following is the same equation solved for f in terms of S?


f=3 /S+22

f=S22/3
f=S/3+22
f=S+22 /3

Answer 1

D. f=S+22 /3

Explanation:

S= 3fs-22

3f/3=S+22/3

f= S+22/3
