To find the right answer, we have to remember that
[tex]\text{Total cost= Variable cost+ Fixed cost}[/tex]
The variable cost is that which changes, in our case, the variable cost is the price of each jersey. since each cost $23 and it increases as the number of jerseys increases.
Thus, the variable cost will be
[tex]23x[/tex]
The fixed cost is always constant. The fixed cost is the one-time set-up fee of 250.
Thus, we can combine the two costs to get the total cost.
The answer will be:
[tex]\text{Total cost=23x+250}[/tex]
