3-18: Refer to the journal entries made in Practice 3-17. Construct a T-account representing each account impacted by those eight transactions. Post all of the journal entries to these T-accounts. Compute the ending balance in each account. Assume that the beginning balance in each T account is zero.

3-19: Refer to the T-accounts constructed in Practice 3-17 and Practice 3-18. Using the ending balances in those T-accounts, construct a trial balance. Note: The only account that is common to these two sets of T-accounts is the cash account; add the two cash account balances together to get the total balance.
