Answer:
325 adult tickets and 125 child tickets
Step-by-step explanation:
You might need to use a method called Guess and check to do this.
Since they have options, it'll be easier to find.
1st option: 225 adult and 225 child tickets
225 x 6 = 1350
225 x 4 = 990
1350 + 990 = 2250
2nd option: 325 adult and 125 child tickets
325 x 6 = 1950
125 x 4 = 500
1950 + 500 = 2450
So it's the 2nd option.
