00:01
So we're given a graph.
00:01
Ultimately, we want to know the total personnel costs, given that we have the number of workers fluctuating.
00:09
So if we have the number of workers fluctuating, we ultimately want to know the total personnel cost.
00:17
So the way that we're going to do that is multiply it by the cost and then take the area under the curve to get the total number of personnel.
00:24
So the cost, function of x, is going to be 2.
00:34
Because it's a two -day environmental cleanup.
00:37
So we're going to have two times the $11 for the first eight hours of the day from 9 to 5 of f of x, dx, plus 16 .5 times the integral from zero to 24.
01:00
Because they were paid per hour of work the rest of the day.
01:09
So we want to know how much they made as a result.
01:13
And this is going to be from 8 to 24...
