The equation of hyperbola can vary much from simple to complex equation. Since the information given from this question is not many, the equation probably was the simple one. Assuming that the hyperbola formula is y= x^2 +b, then the value of b where x=-2 and y=-3 would be: y= x^2 +b -3= (-2)^2 +b -3= 4+b b=-3 -4= -7
You need to find the difference to show how much profit she makes. Subtract her cost of $413.00 from her selling price of $600.00 it will give you the difference, which is her profit.
