alice invested a portion of $500 at 4% interest and the remainder at 5%.
how much did she invest at each rate if her total income from both investments is $23.28.
Hi,
I tried to solve this and I don't get $162 . can someone please check my working and tell me were I have gone wrong .
thank you
$\displaystyle 0.4x + 0.5(500-x) = 23.38 $
$\displaystyle 0.4x + 250-0.5x = 23.38 $
$\displaystyle -0.1x + 250 = 23.38 $
$\displaystyle -0.1x = -226.62 $
$\displaystyle x = 2266.2 $
?
