Answer:

$40.50

Step-by-step explanation:

Create a proportion using the cost in the numerator and number of tickets in the denominator.

[tex]\frac{18}{4} =\frac{x}{9}[/tex]

cross multiply

162=4x

divide by 4 on both sides

x=40.5

$40.50

Flames177

$40.50

Step-by-step explanation:

4×2=8 tickets

18×2= 36 dollars

1/4 of 18 dollars is 4.5

so 36+4.5= $40.50

This could be wrong-
