The question asks for the number that is 850% greater than 8 × 103. First, determine the value of 8 × 103. That number is 8,000. To 8,000, you need to add 850% of 8,000. Here’s what the math looks like: 8,000 + (850% × 8,000) = 8,000 + (8.5 × 8,000) = 8,000 + 68,000 = 76,000 In scientific notation, this is 7.6 × 104, choice (D).
