Question 45978: Lane invested $22,000, part at 8% and part at 7%. If the total interest at the end of the year is $1,710, how much did she invest at 8%? Answer by Nate(3500) (Show Source):
You can put this solution on YOUR website! 0.08(x) + 0.07(22000 - x) = 1710
0.08x + 1540 - 0.07x = 1710
0.01x = 170
x = 17000
$17,000 in 8%
