Question 134157: An investment of $1500 paid interest of $45 during a certain period. How much interest would an investment of $2000 invested at the same rate for the same length of time pay? Answer by nycsharkman(136) (Show Source):
You can put this solution on YOUR website! Set up a proportion and solve for x.

$90,000 = $1500x
$90,000/$1500 = x
$60 = x
