To create a supply schedule for a fruit smoothie shop, you would need the price charged and the number of smoothies supplied. This information allows you to determine how much of the product will be supplied at different price points, which is essential for building a supply schedule.
While knowing about competitors (like the number of other shops producing smoothies and the prices they charge) can provide context and inform your pricing strategy, the core data for constructing a basic supply schedule specifically focuses on your shop's pricing and corresponding supply quantities.
Therefore, the most direct answer would be:
the price charged and the number of smoothies supplied.
