thank you!!! @MrSkipped8thGrade & no just to justify your answer mathematically

Answer 15

which you did

Answer 16

20% of 30 is 6 (for neighborhood A) so every year adds 6 houses

Answer 17

wait i messed up a few times in there let me backtrack

Answer 18

1
A=36
B=48
2
A=42
B=51
3
A=48
B=54
4
A=54
B=57
5
A=60
B=60
Answer is actually 5 years exacly

Answer 19

ok

Answer 20

for part B
neighborhood A has 60 as well as neighborhood B (after 5 years)

Answer 21

is that it?

Answer 22

for part A
neighborhood A
f(x)=30+6x
neighborhood B
f(x)=45+3x
where x = number of years

Answer 23

the first one wouldn't be f(x) = 30 x 0.2x ?

Answer 24

plug in the formula for after 3 years

Answer 25

ok i did I'm going to submit now

Answer 26

f(x) = 30 x 0.2(3)
f(x) = 30 x .6
f(x) = 18
this shows a decrease in houses. obviously not it.
