Step-by-step explanation:
48 adult tickets and 24 children tickets were sold.
Step-by-step explanation:
Given,
Cost of one adult ticket = $8
Cost of one child ticket = $3
Total worth of sold tickets = $456
Let,
Number of adult tickets sold = x
Number of child ticket sold = y
According to given statement;
8x+3y=456 Eqn 1
x = 2y Eqn 2
Putting value of x from Eqn 1 in Eqn 2
Dividing both sides by 19
Putting y=24 in Eqn 2
48 adult tickets and 24 children tickets were sold.

Def the second one because think about it this way 1.5 x 8 = 12
There's your answer
Here is the process:
120/ 2 = 60
60 / 2 = 30
30 / 2 = 15
15 / 3 = 5
Notice that 2, 3 and 5 are all prime numbers
So, 120 = 5*3*2*2*2
