Answer:
The total costs for this month is $1463.75
Explanation:
Consider the provided cost function.
It is given that the cost function for Marisa's new clothing store where she sells T-shirts is C = $9.75n + 1025.
Here, n represents the number of T-shirts Marisa sells.
We need to find the Marisa's costs if she sells 45 T-shirts this month.
To find this substitute the value of n=45 in the above cost function.



Hence, the total costs for this month is $1463.75
