You’re given two dataframes: transactions and products.

The transactions dataframe contains transaction ids, product ids, and the total amount of each product sold.

The products dataframe contains product ids and prices.

Write a function to return a dataframe containing every transaction with a total value of over $100. Include the total value of the transaction as a new column in the dataframe.

Example:

Input:

import pandas as pd

transactions = {"transaction_id" : [1, 2, 3, 4, 5], "product_id" : [101, 102, 103, 104, 105], "amount" : [3, 5, 8, 3, 2]}

products = {"product_id" : [101, 102, 103, 104, 105], "price" : [20.00, 21.00, 15.00, 16.00, 52.00]}

df_transactions = pd.DataFrame(transactions)

df_products = pd.DataFrame(products)

Output:
