Solve, kara's store experienced fixed costs of $200 and variable costs of $4 a shirt. write an equation that can be used to determine the total expenses encountered by kara's

Since the variable cost would be 4, you would multiply the variable of which is given, in this case, x, with 4. 4x

Since it's a fixed cost, you wouldn't touch the 200 and just add it to the 4x to get the total.

f (x) = 4x+200
