Answer:
The amount invested are $2600 and $11400 respectively
Step-by-step explanation:
<em>Let the first amount be x</em>
Given:
(First Investment)
Principal (P1) = x
Rate (R1) = 4.5%
Time (T) = 1 year
(Second Investment)
Principal (P2) = 4x + 1000
Rate (R2) = 6%
Time (T) = 1 year
Income = $801
Calculating the income from the first investment;
Substitute values for P1, R1 and T
Calculating the income from the second investment;
Substitute values for P2, R2 and T
So:
Multiply through by 100
Collect Like Terms
Divide through by 28.5
Recall that; the second invest
Amount Invested = 4x + 1000
This gives
Hence;
<em>The amount invested are $2600 and $11400 respectively</em>
