Answer: Choice A) 8.742 * 10^7

=====================================

Work Shown:

$(a * 10^b) * (c * 10^d) = a*c*10^(b+d)\\\\(2.82 * 10^4) * (3.1 * 10^3) = 2.82*3.1*10^(4+3)\\\\(2.82 * 10^4) * (3.1 * 10^3) = 8.742*10^(7)\\\\$

Extra info:

8.742 * 10^7 = 87,420,000

which is a little over 87.4 million
