Answer:

Option A is correct that is $18

Step-by-step explanation:

We have been given an information that is

c=$54 when n =9

when 9 gives 54

Then 1 gives 54/9

cost for one sandwich that is when n=1 then $c=\frac{54}{9}=6$

We need to find the cost for 3 sandwiches that is when n =3 then

when cost for one sandwich is 54/9 then cost for 3 sandwiches is $3\cdot \frac{54}{9}=18$

Therefore, Option A is correct tha is $18.
