In this question, first we need to calculate the total number of hours, the total number of hours worked by each group of accountants, the total number of hours worked by each group, each group of accountants.
00:24
So, we are given that the early, the early career accountants, the early career accountants is 15 times the hours worked, 15 times of hours worked, where the mid -career accountants, the mid -career accountants is given as 10 multiplied by hours worked, 10 times the hours worked and the senior accountants is 4 times of hours worked.
01:13
So, here we don't have information about the number of hours worked.
01:17
So, we cannot calculate the total number of hours.
01:20
However, we can assume that each group worked the same number of hours.
01:24
For example, let's say 100 hours each.
01:28
This is just an assumption, but this will allow us to calculate the weighted mean.
01:33
So, using this assumption, we can calculate the total number of hours worked by all accountants, number of hours worked by all accountants is calculated as 15 times 100 plus 10 times of 100 plus 4 times of 100.
02:01
So, this will add up to a value of 2500.
02:05
Now, next we need to calculate the total billing amount, the total billing amount for each group of accountants, amount for each group, total billing amount for each group of accountants and this is calculated as early care for early career accountants, we have 15 times of 95 dollars per hour multiplied by the hours worked, the hours worked...
