76.3%
79.4%
84.9%
89.4%
x 68.2%

Explanation:

Step1: Identify the lowest score

The scores are 74, 87, 68, 63, 76. The lowest score is 63.

Step2: Calculate the sum of remaining scores

Sum = 74 + 87+68 + 76=305.

Step3: Calculate the average

Since we dropped one score, there are 4 scores left. Average = $\frac{305}{4}=76.25\approx76.3$.

Answer:

76.3%
