We have been given that in a certain clothing store, 6 shirts and 3 ties cost $79.50. We can represent this information in an equation as:

We are also told that 3 shirts and 2 ties cost $41. We can represent this information in an equation as:

Now, we will use substitution method of solving system of equations. From equation (1) we will get,

Substituting this value in equation (2):

Now, we will multiply both sides of our equation by 2.

Subtracting 79.50 from both sides we will get,

Therefore, the cost of each tie is $2.50 and option A is the correct choice.
