Answer:
C
Step-by-step explanation:
This is a combination question.
In the first instance, we select 5 from 20 and in the second case , we select 4 from 20.
The total number of ways to solve the first instance is 20C5 = 15504 ways
The total number of ways to solve the second instance is 20C4 = 4,845
The ratio of the first to the second scenario is 15,504/4,845 = 3.2 = 16 to 5
Using google calculator you can see that
e≈2.7 1 8 2 8 182846.....
Fifth decimal place is bold 8.
When we round up to 5th decimal place, we get
e≈2.7 1 8 2 8.
D=dollars earned
T=time spent painting the fence.
(1,5) (2,10) (3,15)
D=5T
