Inventory errors misstate closing stock and gross profit

Steps:

• Error 1: Damaged inventory valued at $340 instead of NRV$10, overstates closing inventory by $330, understates COGS by$330, overstates gross profit by $330.
• Error 2: 100 items valued at $7 each ($700 total), excluding carriage $1 each ($100), understates closing inventory by $100, overstates COGS by$100, understates gross profit by $100.
• Net effect: $330 overstatement minus$100 understatement = $230 overstatement in gross profit.
• Note: Question incomplete ("had not been included in" cut off), preventing exact $640 calculation; ambiguous on carriage impact.
