Answer 1

The third answer
Because it has all the math that is right and if you look at the first answer, it doesn’t have the 34 at the end. The second answer is wrong because it did 3 times 1 not ten and it says 734 not 703

Answer 2

(C) 8 x 10,000 + 3 x 1,000 + 7 x 100 + 3 x 10 + 4 x 1 + 2 x 0.1 + 1 x 0.01

Explanation:

8 x 10,000 + 3 x 1,000 + 7 x 100 + 3 x 10 + 4 x 1 + 2 x 0.1 + 1 x 0.01=

80,000 + 3,000 + 700 + 30 + 4 + 0.2 + 0.01=

83,734.21.

I hope this helps!
