<h2>
Answer: ( 3.5 , 7.5 )</h2>
Step-by-step explanation:
Mid-point = [ ((x₁ + x₂) ÷ 2) , ((y₁ + y₂) ÷ 2) ]
= [ (-5 + 12) ÷ 2] , [(10.5 + 4.5) ÷ 2]
= ( 3.5 , 7.5 )
This is a system
x is the number of advanced tickets sold
y is the number of same day tickets sold
once you label your variables then write the equations
x+ y = 45 total tickets sold
20x + 25y = 1050 money taken in
multiply the top equation by -20 and the x will drop out
-20x - 20y = -900
20x + 25y = 1050. Add the equations result is
5y = 150, divide by 5 ,
y or same day tickets cost $30
substitute 30 into first equation
x + 30 = 45 therefore x = 15
