$9.50 times 5 people equals $47.50, plus the fee of $1.25, equals $48.75. With only $1.25 left over after that, you could not afford to pay for any more tickets for others to see the movie.
At most, 4 people would be able to watch the movie including yourself. The price of 4 people is $41. If you would do more than 4, for example 5 it would be $53.25.
since the proportion is already 4:6, so you want to divided it by 2, so it will become 2:3, then multiply it by 7, so thats how i got 14 tomatoes for 21 people
