Can someone answer this for me

Question

Kara's Custom Tees experienced fixed costs of $400 and variable costs of $5 a shirt. Write an equation that can be used to determine the total expenses encountered by Kara's Custom Tees. Let x be the number of shirts, and let C(x) be the total cost of producing x shirts. Then, calculate the cost of producing 6 shirts.

Answer 1

C(n) = 400 + 5n  where n = # of T-shirts, C(n) is total cost to make/acquire n T-shirts.  I used n because that suggests this value must be an integer (non-negative, also).

 

You can compute C(6) now.

 

 

Answer 2

C(x) = 400 + 5x

 

Can you calculate when x = 6?
