Kevin invested his savings in two investment funds. The amount he invested in Fund A was $3000 less than the amount he invested in Fund B. Fund A returned a 8% profit and Fund B returned a 5% profit. How much did he invest in Fund A, if the total profit from the two funds together was $1320?

Answer 1

if $x in A, then x+3000 was in B.

.08x + .05(x+3000) = 1320
