Using Python 3:

The original U.S. income tax of 1913 was quite simple. The tax was

1 percent for the first $50,000

2 percent on the amount over $50,000 up to $75,000.

3 percent on the amount over $75,000 up to $100,000.

4 percent on the amount over $100,000 up to $250,000.

5 percent on the amount over $250,000 up to $500,000.

6 percent on the amount over $500,000

Write a function name tax_1913 that compute the income tax according to this schedule and show your output for an income of $89,000 and $278,000
