Hello students.
00:01
Today we will discuss about this question.
00:04
In this question we have given that a two -day environmental cleanup started at 9 a .m.
00:10
On the first day and the number of workers fluctuated as shown in the following figure.
00:19
And suppose that the worker were paid $17 per hour for work during the time period 9 a .m.
00:30
To 5 p .m.
00:30
To 5 p.
00:30
And were paid $25 .5 per hour for work during the rest of the day.
00:42
Then what would the total personal cost of the cleanup have been under these conditions? here we need to find the total cost.
00:56
That is equals to question 1.
00:59
So here we can say that from the graph, the first four, hours there were 40 plus 50 divided by 2 that is equals to 95 divided by 2 that is equals to 48 workers now for next 8 hours there were 50 plus 40 divided by 2 that is equals to 45 workers now next 8 hour there were 40 workers and next 16 hours there were 40 plus 50 divided by 2, sorry, 40 plus 45 divided by 2, that is 85 divided by 2, so that is nearly equals to 42 workers.
01:57
Now, according to the time here, we can say 9 a .m.
02:05
To 1 p .m.
02:06
That is equals to 48 workers 1 p .m.
02:10
To 5 p .m.
02:11
Is equals to 45 workers 5 p .m.
02:15
To 9 p .m.
02:17
To 9 p .m.
02:22
To 5 a .m.
02:23
To 9 a .m.
02:24
To 5 a .m...
