Adrienne invested a total of $2900.00 in two simple-interest money market accounts. Account A paid 3% annual interest and accoun

t B paid 5% annual interest. The total amount of interest she earned after one year was $133.00. If a represents the amount invested in dollars in account A and b represents the amount invested in dollars in account B, the system of equations a + b = 2900.00 0.03a + 0.05b = 133.00 can be used to represent this situation. How much did Adrienne invest in each account? Adrienne invested $ in account A and $ in account B.

Solving the system of equations, it is found that Adrienne invested $1,366.67 in account A and $1,533.33 in account B.

<h3>System of equations:</h3>

The variables are:

  • Variable A: Amount invested in account A.
  • Variable B: Amount invested in account B.

The equations are:

a + b = 2900

0.03a + 0.05b = 133

From the first equation:

a = 2900 - b

Replacing on the second:

0.03a + 0.05b = 133

0.03(2900 - b) + 0.05b = 133

0.03b = 46

b = \frac{46}{0.03}

b = 1533.33

Then, on the <em>first </em>equation:

a = 2900 - b = 2900 - 1533.33 = 1366.67&#10;

Hence, Adrienne invested $1,366.67 in account A and $1,533.33 in account B.
