Answer:
B. Slope = $10.25/shirt
Step-by-step explanation:
C = $10.25n + $1125
In the cost function above , $1125 is the starting cost, before Michelle sells any T-shirts. It is a constant, not a slope.
The slope is a number that you multiply by the number of shirts. It represents the cost per shirt.
The slope is $10.25/shirt.
