Answer:
The amount of ending inventory on 31 December is $2,730
Step-by-step explanation:
Under First-in-first-out method, the company sell the old products than the new
In the given question,
On 31 Jan it purchase 100 units for $30 = 100 units × $30 = $3,000
On 28 Feb it purchase 130 units for $39 = 130 units × $39 = $5,070
And, from 1 march to 31 December it sold 160 units for $45 each
The 160 units could be taken from
100 units × $30 = $3,000
And remaining 60 units × $39 = $2,340
So, the remaining units i.e 70 units (130 units - 60 units) would be closing inventory units
So, the closing inventory = 70 units × $39 = $2,730
