Answer 2

It seems like you've provided a mathematical expression with multiplication and decimals. Let's calculate it step by step:

1. $2.06 \times 3.05$ Result: $6.283$

2. $21.28 \times 3.5$ Result: $74.48$

So, the expression $2.06 \times 3.05 + 21.28 \times 3.5$ equals $6.283 + 74.48 = 80.763$.
