Answer:
102
Step by step explanation (if non-calculator):
Times 8.5 by 10 to make 85. This'll now be 85 x 12.
If you can work this out, do so.
If not, then do 85 x 10 = 850.
Then, 85 x 2 = 170.
170 + 850 = 1020.
Now, divide 1020 by 10, since you multiplied 85 by 10 at the beginning.
1020 ÷ 10 = 102!
