To find the right answer, we have to remember that
![\text{Total cost= Variable cost+ Fixed cost}](https://img.qammunity.org/2023/formulas/mathematics/college/76he6u83r35rb1r1ve82dv6j0kj8zzd2wr.png)
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
![23x](https://img.qammunity.org/2023/formulas/mathematics/college/6ddwfaf2xwvgqm9rccft5510848ffbxwqz.png)
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:
![\text{Total cost=23x+250}](https://img.qammunity.org/2023/formulas/mathematics/college/ckl4ad4ooxg2wdsoitvtukdikgqaztuato.png)
