Answer:
x = 12
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180, that is
9x + 11 + 3x - 15 + 2x + 16 = 180, simplify left side
14x + 12 = 180 ( subtract 12 from both sides )
14x = 168 ( divide both sides by 14 )
x = 12
The cost is $100. Take $325, and subtract $125. It gives you $200. And you have to divide that in half cuz the price is twice the cost. So the cost is $100

5+15=20
20x3=60
I'm probably wrong, but thats how I understood the question.
