the figure above shows a stores supply - demand graph for coffee makers. if the store sells $375 worth of…

Explanation:

Step1: Recall revenue formula

Revenue = Price × Quantity. We know Revenue = $375$, so Quantity = $\frac{375}{\text{Price}}$. We need to check which price - quantity combination is on the supply - demand graph.

Step2: Check option a

If Price = $15$, then Quantity = $\frac{375}{15}=25$. Looking at the graph, at a price of $15$, the quantity demanded is much more than 25 and the quantity supplied is much less than 25, so this is not a valid point on the supply - demand equilibrium.

Step3: Check option b

If Price = $25$, then Quantity = $\frac{375}{25}=15$. Looking at the graph, at a price of $25$, the quantity demanded is greater than 15 and the quantity supplied is less than 15, so this is not a valid point on the supply - demand equilibrium.

Step4: Check option c

If Price = $40$, then Quantity = $\frac{375}{40}=9.375$. Looking at the graph, at a price of $40$, the quantity demanded is less than 9.375 and the quantity supplied is greater than 9.375, so this is not a valid point on the supply - demand equilibrium.

Step5: Check option d

If Price = $55$, then Quantity = $\frac{375}{55}\approx6.82$. Looking at the graph, at a price of $55$, the quantity demanded is less than 6.82 and the quantity supplied is greater than 6.82. Also, we can estimate from the graph that there is a point on the supply - demand curve that could potentially match this price - quantity relationship for the given revenue.

Answer:

d. $55$
