Question

Tickets to the end of year carnival are $18 for 4 tickets. What
is the cost of 9 tickets?

Answer 1

$40.50

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-

Answer 2

$40.50

Explanation:

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

`(18)/(4) =(x)/(9)`

cross multiply

162=4x

divide by 4 on both sides

x=40.5

$40.50
