Explanation:

Step1: Identify initial and melted amounts

Initial snow - pack depth is 6 inches, melted amount is $2\frac{1}{2}$ inches.

Step2: Calculate remaining snow - pack

Subtract melted amount from initial amount. $6 - 2\frac{1}{2}=6-\frac{5}{2}=\frac{12}{2}-\frac{5}{2}=\frac{12 - 5}{2}=\frac{7}{2}=3\frac{1}{2}$ inches.

Answer:

C. $3\frac{1}{2}$
