To find out how many pounds of berries Trudy picked in total, we need to add the amounts she picked in the morning and afternoon.
Morning picking: 6.92 pounds
Afternoon picking: 7.56 pounds
Now, let's add these two amounts together:
\[ 6.92 + 7.56 \]
We'll do the addition step by step:
- Add the numbers in the hundredths place: \(0.92 + 0.56 = 1.48\)
- Add the numbers in the whole number place: \(6 + 7 = 13\)
- Combine the sums:
\[ 13 + 1.48 = 14.48 \]
Thus, the total amount of berries Trudy picked is
\[ \boxed{14.48} \text{ pounds}. \]
