Nina is 64. I hope this is correct , let me know if it isn’t .
-2x^2 + 500x - 350
You need to plug in the equations for C(x) and R(x) into the equation P(x)= R(x) - C(x) and solve.
Answer:

Step-by-step explanation:
To find the slope of the line of the graph, pick any 2 points on the line as your coordinate pairs.
Thus, on the line, let's pick 2 points as our coordinate pairs at:
When x = -6, y = 5 => (-6, 5), and
When x = 3, y = -1 => (3, -1)
Let (-6, 5) be (x1, y1), and (3, -1) be (x2, y2)





Answer:
estimate: $80
exact amount paid: $82
Step-by-step explanation:
If you round $246 to 240, then divide it by 3, you should get $80. The cost per pair should be around $80 each
For the exact answer you take the amount spent (246) and divide it by the amount of jeans she bought (3).
246/3 = 82
