Answer:
remain constant.
Step-by-step explanation:
The short run is a period where all factors of production are fixed. In the short run, a firm would continue to produce if price is above average variable cost. If this is not the case, it would shut down
The long run is a period where all factors of production are varied. It is known as the planning time for a company
Fixed costs are costs that do not vary with output. e,g, rent, mortgage payments
If production is zero or if production is a million, Mortgage payments do not change - it remains the same no matter the level of output.
