$6,000 dollars is invested in two different accounts earning 3% and 5% interest...
the 2 values invested are x and 6000-x
interest=principal times rate times time
time is 1 year so t=1
r=0.03 ad 0.05
we want to find 5% so x is wha we solve for
the interests are
0.03(6000-x) and 0.05x
they add to 220
minus 180 both sides
divide both sides by 0.02
$2000 was invested at 5%
care to share were the trapezoid shown is ?
