Problema Solution
Susan invested her savings in two investment funds. The amount she invested in Fund A was 7000 less than the amount she invested in Fund B. Fund A returned a 4% profit and Fund B returned a 6% profit. How much did she invest in Fund A, if the total profit from the two funds together was $1920 ?
Answer provided by our tutors
Let
x = the amount Susan invested in Fund A
y = the amount susan invested in Fund B
x = y - 7000
0.04*x + 0.06*y = 1920 (profit from A + profit from B = the profit together)
by solving this system of equations we find
x = $15,000
y = $22,000
Susan invested $15,000 in Fund A.
