Answer:
x= 35000
y= 19000
Step-by-step explanation:
The investment in this question divided into two parts, first who earns 5.5% interest(X) and second who have 4% interest (Y).
The total interest gained is $2685 so you can get this equation.
0.055 x + 0.04 y = 2685
Both x and y sum is $54,000 so you can get this equation
x + y = 54,000
y=54000- x
If you combine both equations
0.055 x + 0.04 y = 2685
0.055 x + 0.04 (54000- x) = 2685
0.055 x + 2160- 0.04x = 2685
0.015x= 2685- 2160
0.015x= 525
x=35000
y=54000- x
y= 54000-35000
y=19000
