Answer

Explanation:

Step1: Recall profit formula

Profit = Total Revenue - Total Cost

Step2: Identify revenue term

In $P = 7.5n - (2.25n + 15)$, total revenue is $7.5n$.

Step3: Find per-unit price

Total Revenue = Price per unit × Number sold. So $7.5n = \text{Price} \times n$. Divide both sides by $n$: $\text{Price} = 7.5$

Answer:

$7.50
