Final answer:
The student's question seems to mix topics; while forecasting gasoline sales with moving averages is mentioned, the provided information focuses on the supply curve and law of supply for gasoline, which indicates that higher prices lead to higher quantities supplied. To forecast using moving averages, historical sales data would be used to calculate averages over set periods to identify trends.
Step-by-step explanation:
The student's question is regarding the use of moving averages to forecast gasoline sales, although the additional information provided seems to cover the supply curve for gasoline, not necessarily focusing on moving averages.
To answer the implied question about forecasting gasoline sales using moving averages, one would typically collect historical sales data and calculate averages over a defined period (e.g., 3-month, 6-month moving averages) to smooth out fluctuations and identify trends.
However, the information provided details the supply schedule and how a supply curve is constructed, illustrating the law of supply where a higher price is associated with a higher quantity supplied, using the supply schedule data and indicating an upwards slope on a graph.
