Hope this helps!
I believe in the 20th century, if you need an exact date reply with yes!
X= -4
Y= 8
I would do an explanation but there’s too many parts and it’s very long and most likely complicated to understand also, but yeah

Answer: After 5 hours, Mary will be at the break even point.
To answer this question, we need to find the time when the cost equals the revenue.
Therefore, set our equations equal to each other and solve.
20 + 30h = 10h^2 - 80
0 = 10h^2 - 30h - 100
0 = h^2 - 3h - 10
0 = (h - 5)(h + 2)
Our solutions are h = 5 or h = -2. Only 5 hours makes sense in the context of this problem.
