#A

What is the real- world meaning of the first equation?

The first equation is: 2x+3y=13.50

  • The real world meaning of this is that the cost of two adult tickets plus cost of three student tickets is 13.5 dollars

Solve this system of equations using the substitution method.

[tex] 2x + 3y = 13.50 \\ 3x + 2y = 16.50[/tex]

  • [Solve the second equation for x]

[tex]2x + 3y = 13.50 \\ x = 5.5 - \frac{2}{3} y[/tex]

  • [Substitute the given value of x into the first equation]

[tex]2(5.5 - \frac{2}{3} y) + 3y = 13.50[/tex]

  • [Solve the equation for y]

[tex]y = 1.5[/tex]

  • [Substitute the given value of y into the second equation]

[tex]x = 5.5 - \frac{2}{3} \times 1.5[/tex]

  • [Solve the equation for x]

[tex]x = 4.5[/tex]

  • [The possible solution of the system is the ordered pair (x,y)]

[tex](x,y)=(4.5,1.5)[/tex]

What are the prices of adult and student tickets?

  • X is representing the cost of 1 adult ticket, When we solved the equation we got the value of x as 4.5 that means the cost of an adult ticket is $4.5...~
  • Y is representing the cost of 1 student ticket, When we solved the equation we got the value of y as 1.5 that means the cost of an student ticket is $1.5...~
