To find the average time it took Janette to fold and put away the four items, we'll first need to sum the times for each item and then divide by the number of items.
The times for each item are:
- Shirt: 26.1 seconds
- Sweater: 24.3 seconds
- Pants: 32.8 seconds
- Scarf: 18.2 seconds
Let's add these times together:
\[ 26.1 + 24.3 + 32.8 + 18.2 = 101.4 \text{ seconds} \]
Now, we divide this total time by the number of items, which is 4:
\[ \text{Average time} = \frac{101.4}{4} = 25.35 \text{ seconds} \]
Therefore, the average time it took Janette to fold and put away all four items is:
25.35 seconds
So the correct answer is:
25.35 seconds
