The cost, c, of a ham sandwich at a deli varies directly with the number of sandwiches, n. if c = $54 when n is 9, what is the cost of the sandwiches when n is 3? a.$18 b.$21 c.$27 d.$48

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

when cost for one sandwich is 54/9 then cost for 3 sandwiches is

Therefore, Option A is correct tha is $18.
