Answer:
C(X) = 4.50 X + 500 is the cost for producing X t -shirts.
Explanation:
The fixed production cost = $500
Let the number of t shirts produced each month = X
Cost of production of each T shirt = $4.50
Selling price of each shirt = $11.50
Now, The cost of production of X shirts
= X times ( Cost of each t shirt production) + Fixed Production Cost
= X ( $4.50) + $500
= 4.50 X + 500
or C(X) = 4.50 X + 500 is the cost for producing X t shirts.
