First we are going to calculate how much she paid for the $150000 when she was 35 years old
[tex]\frac{150000}{1000}\cdot6.17=150\cdot6.17=925.5[/tex]Now we calculate how much she is going to pay now that she is 45
[tex]\frac{150000}{1000}\cdot8.63=150\cdot8.63=\text{ 1294}.5[/tex]Then she will pay 1294.5-925.5=369 dollars more
