Answer:
Step-by-step explanation:
rate = 3.5% per month
A) Six days later the bank calculated the daily interest.
so, time = 6 days
= 6 / 30 = 1/5 month
simple interest [tex]=\frac{P*r*t}{100}[/tex]
[tex]=\frac{5000*3.5*1/5}{100} \\\\=35[/tex]
=35%
B) For $5000, t = 1 month
For $2000, t = 20 / 30 = 2/3 month
For $8000, t = 16/30 months
Simple interest for $5000
[tex]=\frac{500083.5*1}{100} \\\\= 175[/tex]
$175
Simple interest for $2000
[tex]=\frac{2000*3.5*2/3}{100} \\\\=\ 46.67[/tex]
=$46.67
Simple interest for $8000
[tex]=\frac{8000*3.5*16/30}{100} \\\\=149.33[/tex]
=$149.33
Total amount in account at the end of 30 days is
= $5000 + $175 + $2000 + $46.67 + $8000 + $149.33
= $15371
