Answer:

f^-1 represents the number of hours the bacteria developed
Step-by-step explanation:

To find inverse of a function , replace f(t) with y

replace t with y and y with x

solve for y
divide both sides by 100

take ln on both sides

divide both sides by ln

multiply by 3 on both sides

Replace x with t and y with f^-1

f^-1 represents the number of hours the bacteria developed
1/3 because if you dived 7 by both of them by you would get 1/3

Carl is incorrect. Dave ate a higher fraction of snack bars, by 0.2 snack bars.
Carl had .5 left of a snack bar.
Dave had .3 left of a snack bar.
Tony had .5 left of a snack bar.
Gary had .0 left of a snack bar.
Tryone had .7 left of a snack bar.
If we add the above snack bars, there is a total of two remaining snack bars, meaning they only ate 12 of 14 snack bars.
