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.
