To estimate the total cost of Marian's shopping trip, we can round each expense to the nearest whole number:
- Clothes: **56.17** can be rounded to **56**.
- Books: **44.98** can be rounded to **45**.
- Meal: **21.15** can be rounded to **21**.
Now, sum the rounded amounts:
\[
56 + 45 + 21 = 122
\]
Therefore, the best estimate of the total cost of Marian's shopping trip is **$122**.
