Answer 2

Since, c varies directly as n, the cost of the sandwiches when n equals to 3 is 18.

What is variation?

Variation is defined by any change in some quantity due to change in another.

Therefore,

c ∝ n

c = kn

where

k = constant of proportionality

Therefore,

54 = 9k

k = 54 / 9

k = 6

Therefore, when n = 3 , c = ?

c = 6 × 3

c = 18
