The amount that should be invested in the account that yields a 4% interest is $10,000.
The amount that should be invested in the account that yields a 3% interest is $5,000.
<h3>What are the linear equations that represent the question?</h3>
a + b = 15,000 equation 1
0.04a + 0.03b = 550 equation 2
Where:
a = amount invested in the account that yields a 4% interest
b = amount invested in the account that yields a 3% interest
<h3>How much should be invested at each rate?</h3>
Multiply equation 1 by 0.04
0.04a + 0.04b = 600 equation 3
Subtract equation 2 from equation 3
0.01b = 50
b = 50 / 0.01
b = 5000
Subtract 5000 from 15,000
15000 - 5000 = 10,000
