Fixed costs are called fixed for a reason, no matter how many hot dogs Jackie sells, she will still have the $200 of fixed costs. An example of a fixed cost that she can have is a permit for selling food from a stand. If the permit cost $200 she will always have to pay that $200, even if she sold absolutely no hot dogs. Variable costs tend to fluctuate depending on the amount of products she produces. As for your question, if you haven't thought of an answer this far, Jackie's fixed costs are $200.
