Hi from Just Answer. I'm PDtax, and will assist.
1. Average fixed cost (AFC): Will go up if fixed cost increases.2. Average variable cost (AVC): No effect, because it is an independent variable.3. Average total cost (ATC): Will go up if fixed costs increases.4. Marginal cost (MC): Will remain the same up as fixed cost increases.
now to slopes:
If fixed cost rises (FC), this causes movement on our graph, however it is a straight line.Total costs (TC) and variable costs (VC) are upward sloping, and are parallel to one another.Average fixed cost (AFC) and average costs (AC) are also upward sloping.Average total cost (ATC) is upward sloping from the intersection point of marginal cost.Marginal costs (MC) is upward sloping, however is based upon change in total costs (quantity produced changes by one unit); it is NOT based upon fixed costs.
Thanks for asking at Just Answer. Positive feedback rating my assistance is appreciated, as it closes out the question and credits me with assisting. I'm PDtax.
