First, find the interest percentage. Divide the amount borrowed by the interest amount.
[tex]\frac{100}{10}=10[/tex]
Then, divide the result by 100% to express it as a percentage.
[tex]\frac{10}{100}=0.10[/tex]
Once we have the interest percentage as a decimal number, multiply it by the new borrowed amount.
[tex]0.10\times1100=110[/tex]
Therefore, you owe $110 at the end of the five weeks.
