Test Case 1: For each bill payment, one receives 10 CRED coins. Chef pays 10 bills using CRED. Thus, he receives 100 CRED coins. Chef can get 1 bag from the CodeChef store using these coins.

Test Case 2: For each bill payment, one receives 20 CRED coins. Chef pays 4 bills using CRED. Thus, he receives 80 CRED coins. Chef cannot get any bag from the CodeChef store using these coins.

Test Case 3: For each bill payment, one receives 70 CRED coins. Chef pays 7 bills using CRED. Thus, he receives 490 CRED coins. Chef can get at most 4 bags from the CodeChef store using these coins.
