#### Answer

Interest = 655,875 dollars
Total amount = 920,875 dollars

#### Work Step by Step

I=PRT Let P=265000 dollars , R=8.25% ,T = 30 years
I=265000$\times$8.25% $\times$ 30
Write 8.25% as a decimal
I = 265000$\times$0.0825$\times$ 30
Multiply
I= 655875 dollars
The simple interest is 655,875 dollars.
total amount = principal + interest
total amount=265000+655875 = 920875dollars
Total amount after 30 years will be 920,875 dollars
