Mohammed went to a different movie theater where the relationship between the number of tickets and cost was not proportional. He noticed 3 tickets cost $21.

Sagot :

The cost of 5 tickets at the same rate is $35

From the question, we have that Mohammed bought 3 tickets for $21. This can be written as:

  • 3 tickets =  $21

To get the cost of 5 tickets at the same rate, we can write:

  • 5 tickets = x

Divide both equations to have:

[tex]\frac{3}{5} = \frac{21}{x}[/tex]

Cross multiply

[tex]3x = 5 \times 21\\3x = 105\\x = \frac{105}{3}\\x=35[/tex]

Hence the cost of 5 tickets at the same rate is $35
