Keith borrowed $102 from his dad, and he is paying him back $11 each month

Ideally, he will repay the whole amount of $102 in 10 months where he will pay $11 for first 9 months and $3 in the 10th month.

Given information:

Keith borrowed $102 from his dad, and he is paying him back $11 each month.

So, Keith will pay back his dad an amount of $11 every month till the debt is cleared.

Now, the number of months required by Keith to repay will be calculated as,

[tex]\dfrac{102}{11}=9+\dfrac{3}{11}[/tex]

Now, Keith will need [tex]9+\dfrac{3}{11}[/tex] months to completely repay his debt.

Fraction of month is not an option for repayment. So, he will pay $11 regularly for 9 months which will be $99 in the repayment, and the remaining $3 will be paid by him in the 10th month.

Therefore, ideally, he will repay the whole amount of $102 in 10 months where he will pay $11 for first 9 months and $3 in the 10th month.
