Answer:
33 children
62 adults
Step-by-step explanation:
Set up 2 equations (a=adults c=children)
The first equation will be 3.25(a)+3 = 300.5
The second equation will be a + c = 95
Subtract c from both sides to get:
a = 95 - c
Replace c in the 1st equation to get:
3.25(95-c) + 3c = 300.5
Distribute 3.25 to 95 and -c:
308.75 - 3.25c + 3c = 300.5
Subtract 308.75 from both sides:
-3.25c + 3c = 300.5 - 308.75
Combine like terms:
-0.25c = -8.25
Divide by -0.25
children = 33
Subtract 33 from 95 to get
adults = 62
F(n)=3n-2
Plug in 2 for n. f(2)=3(2)-2=4
