Since '1700' would be 100%, we can simply calculate the percentage she spent by dividing what she spent with her monthly income.

125 / 1700 = 0.0735

Now we multiply this number by 100 to get the total percentage she spent.

0.0735 x 100 = 7.35%

So, no, she did not spend 8% of her monthly income, she only spent 7.35%
