lets call the amount invested in account 1, x and in account 2, y=(8400-x).
:
account 1-----> .0825(x)
:
account 2-----> .05(8480-x)
:
we set these two formula's equal to each other to determine the amounts at which account 1 and account 2 will be equal.
:
.0825x=.05(8480-x)
:
.0825x=424-.05x
:
.1325x=424
:
amount invested at 8.25%
:
amount invested at 5%
