...oo TFW s 11:31 PM 59% D (1 point) The populations, P, of six towns with time t in years are given by 1 P 1300 (1.07) 2 P 1500 (1.183) 3 P 800 (0.73) 4 P 1700 (0.94) 5 P 2300 (0.8) 6 P 600 (1.15) Answer the following questions regarding the populations of the six towns above. Whenever you need to enter several towns in one answer, enter your answer as a comma separated list of numbers. For example if town 1, town 2, town 3, and town 4, are all growing you could enter 1, 2, 3, 4 or 2, 4, 1, 3 or any other order of these four numerals separated by Commas. (a) Which of the towns are growing? (b) Which of the towns are shrinking?

Solution

The towns growing would have
a number larger than 1 inside brackets

So, growing : 1,2,6

----------------------------------------

b) shrinking :
Less than 1

3,4,5

------------------------------------------

c)
Fastest growth :
Obviously 2

1.183 is 1 + 0.183

1 was the original value, 0.183 is the growth value

0.183 is 18.3%

So, growth is :
18.3%

-------------------------------------------

d) Shrinking fastest :
The one with the least value, i.e 0.73

Town 3 is the answer

1 - 0.27

So, it is a 0.27 shrink

aS in 27% shrink

-------------------------------------------

e) Largest initial population :
5 because it has 2300 initial population

--------------------------------------------

f) smallest init population :
6
