Answer:
350
Step-by-step explanation:
Let the number of adult tickets be x, then the number of student tickets sold would be (x–54).
We now have
x+(x–54)=646
2x=700
x=350
Therefore, 350 adult tickets were sold.
31 is the answer because you would do 5 x 3 an that's 15 and if it's squared u technically add 15 a second time
