Question 1102902: Tyra received $13,000 from her bat mitzvah. Her parents convinced her to invest her money into two accounts, one paying 15% and the other pay 4%. After a year she checked her account balance and it totaled $14,125. How much did she invest in each account?

Let n and 13000-n be the amounts invested at 15% and 4%, respectively. Then:
.15(n)+.04(13000-n)=14125-13000=1125
.11n+520=1125
.11n=605
n=5500
5500 was invested at 15%, and 7500 was invested at 4%
