Answer:
a hourly rate is $10.40
b monthly income = 1788.80
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
