Problema Solution
Amy invested her savings in two investment funds. The $2,000 that she invested in Fund A returned a 1% profit. The amount that she invested in Fund B returned a profit. How much did she invest in Fund B, if both funds together returned a 3% profit?
Answer provided by our tutors
let 'x' represent the amount invested in Fund B, then 'x+2000' represents the total amount invested
let 'i' represent the interest earned from Fund B
interest = principal * rate * time
we assume time to be equal to 1
profile from Fund A:
2000*0.01 = 20
0.03(x+2000) = 20 + x*i
...insufficient information to answer this problem - the percentage return on Fund B is missing and required
