This isn't really a fair question. Many people use that 4 weeks equal one month, when that is no an accurate statement.
But if we assume this to be true, anna owes $1.25 per week which will be reduced from her $150 debt. So since she pays 1.25 for each week.....and there are w weeks, you'd get.
M=150-1.25w
Hope this helped.
