Bob received $14,000 inheritance and divided it between a mutual fund that
yielded a yearly return of 5% and a 1-year CD that paid 3.5% annually.
If his total earnings for the year on this investment was $640, how much did
he invest in each of these two funds?
:
Let x = amt invested at 5%
The total was given as 14000, therefore
(14000-x) = amt invested at 3.5%
:
Write a total interest equation in decimal form
.05x + .035(14000-x) = 640
:
.05x + 490 - .035x = 640
:
.05x - .035x = 640 - 490
:
.015x = 150
x =
x = $10,000 amt invested at 5%
:
I'll let you find out the amt invested a 3.5%
:
Check solution by finding the total interest using the two values
