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.

the formula indicates that interest I=(0.09)P
                           for P=10  therefore I=(0.09)10=0.90
                            P=100  therefore I=(0.09)100= 9.0
                             P=1000  therefore I=(0.09)1000=90.  can you do the rest? try them
