Question 1180473



Joseph has $12500 to invest in two different accounts.
x in account 1
12500-x in account 2

Account 1 pays 9% interest and account 2 pays 12%.

9%x  interest in account 1
 12%(12500-x) in account 2

Account 1 pays 9% interest and account 2 pays 12%.

12%(12500-x) =2*9%x 

multiply equation by 100

12(12500-x) =18x

150000 -12x =18x
30x = 150000

x=5000

$5000 at 9%
$7500 at 12%
