Answer:
Step-by-step explanation:
Let x and y represent amounts invested at 6% and 9%, respectively.
y = 3x +58 . . . . . . . the amount invested at 9%
0.06x +0.09y = 1097.19 . . . . . . total interest earned
__
Substituting for y, we have ...
0.06x +0.09(3x +58) = 1097.19
0.33x + 5.22 = 1097.19 . . . . . . . . . simplify
0.33x = 1091.97 . . . . . . . . . . . . subtract 5.22
x = 3309 . . . . . . . . . . . . . . . . divide by 0.33
y = 3(3309) +58 = 9985
$3309 is invested at 6%; $9985 is invested at 9%.

The perimeter of the parallelogram is 14x + 8. You add 3x+9+4x-5+3x+9+4x-5 to get the answer.
The total profit that is earned is 4512.5
<h3>How to solve for the profit that is earned</h3>
100 - q = 0
q = 100
Maximization is where q = 0
MR = mc
100 - q = 5
such that q = 95
Price would be 100 -0.5(95)
= 100 - 47.5
= 52.5
Profit earned would be
= 95*52.5 -5*95
= 4512.5
