Answer:
B. The rate remains the same, even if income increases or decreases.
Step-by-step explanation:
Proportional tex means that the rate of taxes is the same for everyone. It does not change based on someone’s income. Those who earn more pay the same amount of annual taxes as those people whose incomes are low. This system is also called flat taxes.
Some say that this is the way to motivate people to work and earn more, so they can lose less money proportionally to the taxes. Others criticize the proportional tax system as unfair to those who have low incomes.
