Question

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

Answer 1

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
