3. The drama club sold 240 tickets to the play. They sold 20 more student tickets than adult tickets. How many of each type of
ticket did they sell?

Sold student tickets: 130, sold adult tickets: 110

Step-by-step explanation:

Let s = number of student tickets sold,

Let a = number of adult tickets sold.

(It is given that there were 20 more student tickets sold than adult tickets)

(It is given that the total tickets sold is 240)

We can use substitution to find the number of student tickets:

∴110 adult tickets and 130 student tickets were sold.

I hope this helps :)

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
