Step-by-step explanation:
Let x be the amount at 5%
Then 2200 - x is the amount at 3%
<u>The total interest is:</u>
- 0.05x + (2200 - x)*0.03 = 78.50
- 5x + (2200 - x)*3 = 7850
- 5x + 6600 - 3x = 7850
- 2x = 7850 - 6600
- 2x = 1250
- x = 625
<u>Find the amount at 3%:</u>
Step-by-step explanation:

<em><u>C.x=86.113</u></em>
