Jenny invested her savings in two investment funds. The $6000 that she invested in Fund A returned a 10% profit. The amount that she invested in Fund B returned a 3% profit. How much did she invest in Fund B, if both funds together returned a 6% profit?

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3

you,
