Question 359649
Annika invested in a plan that has an APR of 4%. She invested in a 9% APR account $2300 more than she invested in the 4% account. If the total interest from the investments after 1 year is $2677, then what is the total amount that she invested?
----
Equations:
Interest Eq: 
interest + interest = interest
0.04x + 0.09(x+2300) = 2677
Multiply thru by 100
----
4x + 9x + 9*2300 = 267700
13x = 247000
x = $19000 (amt. invested at 4%)
x+2300 = $21300 (amt. invested at 9%)
