Answer:
B. (13-6) n - 55
Explanation:
The number of shirts to be sold is n
The cost to purchase one shirt is $13
The cost of making each shirt is $6
Let's assume the shirt is one
Profit for a Shirt = (13-6)
But then there are no number of shirts
Profit= (13-6)n
But then also, an advert was run for the total shirts combined
Profit= (13-6)n -55
