Answer 2

Answer:

1years:

principal=5000

interest=8/100×5000=400

2years:

principal=5000+5300=10300

interest =8/100×10300=824

3years:

principal=10300+5500=15800

interest =8/100×15800=1264

accumulated interest at the end of 3years =400+824+1264=2488

total amount in a account at the 3years=2488+15800=18288
