An investor invested a total of $1500 in two mutual funds. One fund earned a 4% profit value while the other earned 2% profit. If the investor's profit was $36, how much was in each mutual fund?

jdoe0001 · Answer

let's say, the 2 amounts for each fund are called "a" and "b"

the total amount he invested was $1500, that is, amount "a" plus amount "b" = 1500, that is
$\bf a + b = 1500$

the earned profits are, say 4% from "a", and 2% from "b", is $36, that is

$\bf \textit{to express the percentages in decimals}\
4\% = \cfrac{ 4 }{ 100 } \implies 0.04\
2\% = \cfrac{ 2 }{ 100 } \implies 0.02$

$\bf 0.04\times a + 0.02\times b = 36 \implies 0.04 a + 0.02 b = 36$

if we know that say,    a + b = 1500 , can you solve that for say... "b", what would it look like?
