Answer: $159,000
Step-by-step explanation:
First find out the accumulated expenditure.
You do this by adding up the expenditures of the different months. These expenditures will be weighted by the number of months they were incurred for the year:
= (620,000 * 12/12 months) + (672,000 * 10/12) + (552,000 * 5/12) + (720,000 * 3/12) + (420,000 * 0/12)
= $1,590,000
Amount of interest capitalized = Accumulated expenditure * interest rate
= 1,590,000 * 10%
= $159,000
