In a savings account at Ace Savings, Julie had some money that earned 6.5% interest. She had $400 more than that amount in a savings account at Busby Federal. The amount in Busby's earned 7.5% interest. How much was invested in each account if her income from the two accounts was $130.80?
------------
Let amount invested at 6.5% be x ; interest earned is 0.065x
Amount invested at 7.5% is x+400; interest is 0.75(x+400)=0.075x+30
--------------
EQUATION:
int. + int. = 130.80
0.065x+0.075x+30=130.80
0.14x=100.80
x=$720 (amount invested at 6.5%)
x+400=$1120 (amount invested at 7.5%)
