Answer 1

Answer:

Explanation:

1. 40.08 + 35.45(2) = 110.98

2. 14.01 + 1.01(5) + 16.00 = 35.06

3.  107.87 + 12.01(2) + 1.01(3) + 16.00(2) = 165.91

4. 137.33(3) + 30.97(2) + 16.00(8) = 601.93

5. 26.98(2) + 16.00(9) + 12.01(3) = 216.06

6. 65.39 + 14.01(2) + 16.00(6) = 189.41

Check me if I'm wrong.
