Answer:
$420,000
Explanation:
The estimated cost of inventory is calculated as;
= (Beginning inventory at cost + purchases at cost ) ÷ (Beginning inventory at retail + Purchases at retail)
= ($360,000 + $900,000) ÷ ($750,000 + $1,350,000)
= 0.60; ($2,100,00 - $1,400,000) × 0.60
= $420,000
Therefore, the estimated cost of the ending inventory is $420,000
