Non-linear effects

Since 2017, the percentage rate of flat-rate expenses has been increased from 40% to 60% of the total income. The monthly limit (420 euros) has been cancelled and the annual limit of the sum of flat-rate expenses is increased from 5 040 euros to 20 000 euros. The changes in the flat-rate expenses are a consequence of the adoption of the law no. 341/2016 Coll., which amended the law no. 595/2003 Coll. on income tax as amended (hereinafter only "income tax act").

Calculate:
a) the minimum total income at which the ceiling of 20 000 EUR on flat-rate expenses is applied
b) what is the real percentage rate of flat-rate expenses at a total income of 40 000 EUR
c) what is the real percentage rate of flat-rate expenses at the maximum possible total income (i.e. 49 790 EUR, the exceeding of which makes the taxpayer a VAT payer and he cannot apply flat-rate expenses)?
