Explanation:

Step1: Calculate sums inside parentheses

First sum: $3 + 0.07 = 3.07$
Second sum: $9.9 + 0.08 = 9.98$

Step2: Multiply the two results

$3.07 \times 9.98$
Breakdown the multiplication:
$3.07 \times (10 - 0.02) = 3.07 \times 10 - 3.07 \times 0.02$
$= 30.7 - 0.0614$

Answer:

$30.6386$
