Answer:
Alex
Step-by-step explanation:
A flat tax system applies a uniform tax rate to all levels of income. Individuals with low-incomes pay taxes at the same rate as those with a high income.
The flat-rate system places a higher burden on individuals with a low income. After the tax is deducted, they remain with relatively less disposable income as compared to an individual with high income. Alex will have the highest tax burden. He earns almost ten times less than Beatrice, yet they pay taxes at the same rate.
