Question 987269: Express each statement as an equation where k represents the constant of variation.
1. The fare F of a passenger varies directly as the distance d of his destination.
2. The cost C of fish varies directly as its weight w in kilograms.
3. An employee�s salary S varies directly as the number of days d he has worked.
4. The rate r at which a person types a certain manuscript varies inversely as the time t spent in typing.
5. The cost c per person of renting a private resort varies inversely as the number n of persons sharing the rent.

Hi there,
1) F = kd
2) C = kw
3) S = kd
4) r = k/t
5) c = k/n
Incidentally, if you have a combination
for example:
D varies directly as P and inversely as Y
This would be:-
D = kP/Y
(k is always on the top line)
Hope this helps :-)
