Answer:
a hourly rate is $10.40
b monthly income = 1788.80
Step-by-step explanation:
We need to make 21 630 per year
The question says a working year has 2080 hours
to find the hourly rate, take the salary and divide by the hours
21630/ 2080 hours = 10.40 per hour ( rounded to the nearest cent)
So the person will be making 10.40 per hour
There are 172 hours in a month
Salary = hours * rate
=172*10.40
=1788.80

{2} would be the first subset; it contains one even number.
Next would be {2, 4}, next {2, 4, 6} ... {2, 4, 6, ... 94, 96, 98, 100}. Provided that we correctly understand what this problem is asking for, writing out and then counting all these subsets should answer the question.
