The amount of the 9% note is ?

The amount of the 7% note is ?

Answer provided by our tutors

Total Amount = $180,000

Total Interest = $14,600

Amount to be paid off at 9% = x

Amount to be paid off at 7% = 180,000 - x 

Amount to be paid off at 9% * 9% + Amount to be paid off at 7% * 7% = Total Interest

x*9/100 + (180000-x)*7/100=14600

x*0.09+(180000-x)*0.07=14600

0.09x+12600-0.07x=14600

0.02x=14600-12600

0.02x=2000

x=2000/0.02

x=100,000 


Amount to be paid off at 9% = x = $100,000

Amount to be paid off at 7% = 180,000 - 100,000 = $80,000 


Check

100000 * 0.09 + 80000 * 0.07 = 14600

9000+5600=14600

14600=14600
