Answer:
Determine the total interest cost under each plan.
Plan 1 220320
Plan 2 224280
Step-by-step explanation:
FIRST
F = P ( 1 + i * n )
F=720000(1+10,20%*3) 940320
F=940320
Interest=940320-720000 220320
Interest 1= 220320
SECOND
F = P ( 1 + i * n )
Interest 2
F=720000(1+8,5%*1) 781200 720000 61200
F=720000(1+12,9%*1) 812880 720000 92880
F=720000(1+9,75%*1) 790200 720000 70200
224280
