A woman borrows 100000 euro to improve her house. she borrows the money at 15% interest and repays it in full after three years. What interest will she pay?
PLEASE HELP

100,000 * 0.15 * 3 = ?

I thought it is suposed to be like this:
15/100*100,000 then you get the answer and the asnwer you get add with the number you multiplied with do the same thing for three times? Is it like that? 
My answer is 45,000 euros.
What answer did you get? 
well the asnwer according to my book is 520875 and I am gettign the wrong answer. I get 84762.5

I don't see how your book can be right. It doesn't make sense that she'd pay interest of five times the amount of the loan.
Check with your teacher.
