Step-by-step explanation:
If a population is decreasing by 8% we can multiply the population by 92% (1-.08)
which means we have the following equation
population=15000(.92)ⁿ
where n is the number of years
we want to know when the population will be 10,000 so we write
10,000=15,000(.92)ⁿ
.66667=.92ⁿ
a rule we have is
which means that
compute this and get
4.867
round this up to 5
Task 1 ----- 
minutes
Task 2 ----- 3 min 10 sec = 3+10/60 =
minutes
Task 3 ----- 1 min
Total time to make 1 item = + 
+1 = 
minutes
In 25 minutes;
Number of items made = 25/(6 2/3) = 3.75 items = 3 items (since only a fully assembly can be regarded as an item).<span />
