The question in English is
Having organized a bingo has raised $1900. For the entrance of men $15 and women $10 and an attendance of 150 people has been reported. Determine the number of men and the number of women who participated in the bingo.
Let
x----> the number of men
y----> the number of women
we know that

-----> equation A
-----> equation B
substitute equation A in equation B and solve for y





Find the value of x

therefore
The number of men was 
The number of women was 
The equation of a parabola is:

If a>0, then the parabola opens up;
If a<0, then the parabola opens down.
The coordinates of focus are:
