Claudia,
You have to use the weighted average accumulated expenditures for the non-construction specific debt
That is where the .05(156-60) comes from
40,000 * (12/12) = 40,000
120,000 * (10/12) = 100,000
96,000 * (2/12) = 16,000
40,000+100,000+16,000= 156,000 weighted average construction costs
Two interest rates for non-construction specific debt are 4% and 6%, average is 5%
Total construction interest =
Step 1: Construction Specific debt: 60,000 * 0.06 = 3600
Step 2: Non-specific debt: 0.05 * (156,000 – 60,000) = 4800
Note: you subtracted 60,000 because you already considered that 60,000 for the construction specific debt and you don't want to double count interest
Step 3: Add specific and non-specific interest = 3600 + 4800 =8400
