Samuel has to sell concert tickets worth at least $90. The price of a child ticket is $8, and the price of an adult ticket is $1
5. Let y be the number of child tickets sold and x be the number of adult tickets sold. Which of the following graphs best models this situation?
2 answers:
Answer:
The last graph is the best models this situation.
Step-by-step explanation:
First we need to find the equation of ticket selling. To not loss any money from this business Samuel need to sell at least 6 adult or 11.25 child tickets. I know ticket number must be integer but those numbers are x and y values that line crosses through axes. The equation is:
and the graph of this equation is attached.

<h3>Graph of system of linear equations </h3>From the question, we are to graph the given system of equations.
The given system of equation is
y + 2x = −1
3y − x = 4
The graph of the given system of equations is shown below.
From the graph, we can observe that the solution to the given system of equation is given by two lines that intersect at the point (-1, 1).
Hence, the system of equations has one solution (-1, 1)
