The interest on a loan at an interest rate of 9% over a year is I = (0.09)P, where P is the principle (loan amount) and I is the interest rate. Use a domain in the table to find the interest of these amounts for one year. Write the range only in your solution.

Principle 10 100 1000 10,000 100,000 1,000,000
Interest -- -- -- -- -- --
A. {0.09, 0.9, 9, 90, 900, 9,000}
B. {0.9, 9, 90, 900, 9,000, 90,000}
C. {9, 90, 900, 9,000, 90,000, 900,000}
D. {0.1, 1, 10, 100, 1000, 10000}
