The table shows the cost of concessions at a concert. evan spent $31.50
buying popcom for his class. how many bags of popcorn did evan buy?

p= popcorn

x=number of kids in class

c= cost

Plug in data:

c = px

31.5=1.5x

Divide both sides by 1.5:

21= x

There are 21 kids in the class.

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

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
