Answer:
125 adults
175 children
Step-by-step explanation:
3900=8c+20a
300=c+a
c=300-a
substitute
3900=8(300-a)+20a
reduce
3900=2400-8a+20a
1500=12a
a=125 adults
substitute for a
c=300-a
c=300-125
c=175 children

Slope is 1/2
Step-by-step explanation:
Using the slope formula y₂-y₁/x₂-x₁
(x₁,y₁) and (x₂,y₂) → (1,2) and (3,3)
So...
3-2=1
3-1=2
1/2
