The time, in hours, it takes to decorate the school gym for a dance varies inversely as the number of students, , who are helping decorate.
t = k%2Fs, where
t = time in hrs
s = no. of students
k = constant of variation
:
If a group of 7 students can decorate the gym in 7 hours,
Find k
7 = k%2F7
k = 49
: which of the following equations best models the time, , it will take a group of students to decorate the gym?
t = 49%2Fs
