Investing a woman has money in two accounts. one account pays 6% annual interest, whereas the other pays 12% annual interest. if she has $500 more invested in 12% than she does at the 6% and her total interest for a year is $186, how much does she have in each account

Respuesta :

0.06x + 0.12(500+x) = 186

0.06x + 60 + 0.12x = 186

0.18x = 126

x = 700

She invested $700 in the 6% account, and $1200 in the 12% account.
