We can write b= boys, and g= girls

we know that girls are equal g=(2*b-5)
we also know that b+g=40
we will replace girls with the above equation and get
b+ (2*b-5) = 40 , 2*b=2b
b+2b= 40+5
3b=45, divide everything by 5
b=15
girls are 2*15-5=25
15+25=40

Given the function g(x) = 4(3)x, Section A is from x = 1 to x = 2 and Section B is from x = 3 to x = 4.
LenaWriter [7]
Easy peasy


the average rate of change in section A is the slope from (1,g(1)) to (2,g(2))
the average rate of chagne in section B is the slope from (3,g(3)) to (4,g(4))



A.

section A
g(1)=4(3)^1=12
g(2)=4(3)^2=4(9)=36
slope=(36-12)/(2-1)=24/1=24

section B
g(3)=4(3)^3=4(27)=108
g(4)=4(3)^4=4(81)=324
slope=(324-108)/(4-3)=216/1=216



section A has an average rate of change of 24
section B has an average rate of change of 216
