Hey guest! Im pretty sure the scale factor is when you find two corresponding sides then use the ratio right? Well im pretty sure the scale factor in this question is 6:9 which can be simplified into 2:3. Which means that the scale factor is 2:3? I think.

Hey guest! Lets start! First the way I learend it is that you first make it all that he bought kid tickets. If he only bought kid tickets it would cost him $58.50. Then you subtract 69.50 and 58.50 which gets you 11. Then you subtract 9.25 from 6.50 to get 2.75. Then you divide 11 by 2.75 which gets you 4! That means that he bought 4 adult tickets! Lets see if we are correct!

4*9.25=37. Then 6.50*5=32.5. 37+32.50=69.50! So he bought 4 adult tickets!
