To find the number of hours Richard still needs to work to reach 30 hours for the week, we can subtract the hours he has already worked from the target number of hours.
The working equation is:
30 hours - 21.15 hours = h
To solve the equation, we subtract 21.15 from 30 hours:
30 hours - 21.15 hours = 8.85 hours
Therefore, Richard still needs to work 8.85 hours to reach 30 hours for the week.
