Okay so the first one is 3 dollars each..because if you subtract 9 from 21 you will be left with 12 dollars so if he spent the money on FOUR tickets it would be 3 because 3 times 4 is 12 :)

For the first one you subtract 9 from 21 then divide that by 4 and get 3

For the second one (21-9)x2 is how you get your answer which would be 24
