I have two journal entries I need help with.

Merchandise that cost $850 was sold for $965 in cash

Inventory costing $700 was purchased; cash of $500 was paid and the balance is due in 45 days.

First question has two entries

Revenue credit 965

COGS debit 850
Merchandise credit 850

Second scenerio

Inventory debit 700
Cash credit 500
Accounts payable credit 200
