Scott and Laura have both invested some money. Scott invested $2500 more than Laura and at a 3% higher interest rate. If Scott received $900 annual interest and Laura received $450, how much did Scott invest?

Answer 1

s(1+r) = 900
(s-2500)*(1+r-.03) = 450

I get s=10,000, but a negative interest rate. Is there a typo?

Answer 2

no, I copied the question just as it is, there is 2 answers, the $10,000 is the smaller amount he invested, there should also be a larger amount.
