Answer: 71.19
Step-by-step explanation:
Since, the total amount = 678
Total charged on that money = 10.5 %
Thus, the total interest paid = 10.5% of the total amount
[tex]=10.5\% \text{ of } 678[/tex]
[tex]=\frac{10.5}{100}\times 678[/tex]
[tex]=\frac{7119}{100}[/tex]
[tex]=71.19[/tex]
Hence, the total paid interest = 71.19
