Answer:
$210,000
Explanation:
The computation of the external price is shown below
Making cost = buying cost
$120,000 + $25,000 + $45,000 + $30,000) = external price + Unavoidable fixed cost (30,000-20,000)
$220,000 = External price + $10,000
So,
External price = 210,000
Hence, the same is to be considered
Therefore the external price is $210,000
