Answer 2

Option A, 70

Explanation:

Step 1: Find the Science grade

(95 + 85 + 90 + 80 + x) / 5 = 84

Step 2: Multiply both sides by 5

(95 + 85 + 90 + 80 + x) / 5 * 5 = 84 * 5

95 + 85 + 90 + 80 + x = 420

Step 3: Combine all of the numbers

95 + 85 + 90 + 80 + x = 420

350 + x = 420

Step 4: Subtract 350 from both sides

350 + x - 350 = 420 - 350

x = 70

Answer: Option A, 70
