21. Finance Adrienne invested a total of $1900 in two simple-interest money market accounts. Account A paid 3% annual interest and account B paid 5% annual interest. The total amount of interest she earned after one year was $83. If a represents the amount invested in dollars in account A and b represents the a + b= 1900 amount invested in dollars in account B, the system of equations can represent 0.03a + 0.05b= 83 this situation. How much did Adrienne invest in each account?
