Using cross multiplication method,
x -12 -12x
x 2 2x

-24 -10x
Therefore,

=3(x-12)(x+2)
3.50x + 266 = 406
↓
40x
The answer is 40. She needs to sell 40 more bracelets to reach her goal.

Step-by-step explanation:
I could be wrong because I didn’t take business calculus, but i guess it’s the same as regular calculus.
So I assumed that the revenue is equal to the price times the amount produced: R=px
Now differentiating, I get: dR/dt =pdx/dt +xdp/dx. I used the product rule
But Mr. Kong wants his revenue constant ? So I assume that dR/dt=0
Plug in values and solve dx/dt. Please message me back. I want to see if I got it write
Multiply bottom equation by -3 to add and eliminate y’s.
So...
5x-15y=10
+-9x+15y=18
You get -4x=28 so x=-7
Plug in to get y
5(-7)-15y=10
-35-15y=10
-15y=45
So y=-3
Check in other equation
3(-7)-5(-3)=
-21+15=-6
So x= -7 and y= -3
