To solve this, I would just find what two adult tickets and one child ticket wold be worth.
To find that, just do:
5.20 + 9.90 * 2, which makes 25.
So now you just find how many 25s are in 900, or 36.
So 36 children's tickets were sold that day.
Hope I helped :)
Answer:
The domain restriction for (f/g)(x) is x=7

we have
so
Remember that
the denominator can not be equal to zero
so
Find the domain restriction
x-7=0

Answer:
40 years old
16 years old
Step-by-step explanation:
Son = 8 years old
his father is five times as old.
Father = 5 × 8
= 40 years
How old will the father be when he will be twice as old as his son?
Father = 2 × 8
= 16 years
Father:
Five times as old as son = 40 years old
Twice as old as his son = 16 years old
