I have been given the following problem to solve...and I think I am missing a formula. It seems like something I can probably solve by trial and error, but I think that would be missing the point.
I have been given information regarding rates of tax and national insurance contributions in the UK. and asked a question where
Based on deductions made for tax and NI, and 9% loan repayments on any salary over £15000.
how much must a salary be, so that after all deductions, there is a net monthly income of atleast
a)1500 b)2000 c)2500
If anyone knows how to deal with this sort of problem, if there is a formula? (It says in the 'hint' that 'given such formulae completing the calculation is straighforward'
