Final answer:
To calculate the number of bags of potatoes Sage needs to buy, Sage can use the equation Q = (p * d) / C, where Q is the quantity demanded, p is the grams per serving, and C is the capacity of each bag.
Step-by-step explanation:
The goal is to write an equation to help Sage decide how many bags of potatoes to buy for a benefit dinner, considering the number of servings required, the amount of potatoes in each serving, and the capacity of each bag. If Q represents the number of servings of potatoes needed (quantity demanded), p represents the grams of potatoes in each serving, C represents the grams of potatoes in each bag, and d represents the number of bags, we can derive an equation for Q in terms of the other variables.
To find the total grams of potatoes needed, we multiply the number of servings (Q) by the grams per serving (p). To find the number of bags (d) needed, we divide the total grams by the capacity of each bag (C). The correct equation would be:
Q = (p \c.d) / C (Option B),
where dividing the product of the grams per serving and the number of servings by the capacity of each bag will give us the number of bags required.
