Answer:
Step-by-step explanation:
Let x represent the amount invested in the higher-earning account. Then the investment in the other account is (7200-x), and the total interest is ...
0.13x +0.11(7200 -x) = 832
0.02x = 832 -792 . . . . . . eliminate parentheses, collect terms, subtract 792
x = 40/0.02 = 2000 . . . . divide by the coefficient of x
$2000 was invested at 13%; $5200 was invested at 11%.
Equations are: 4x + 2y = 6
x - y = 3
Multiply 2nd equation by 2,
2x - 2y = 6
Add both the equations,
6x = 12
x = 12/6
x = 2
In short, Your Answer would be 2
Hope this helps!
