At Snowflake Plastics, each employee gets 10 sick days and 10 vacation days per year. If Mark uses half his allotment of both types of days in a year, how many hours' worth of days does he have left if each day covers an 8-hour long workday?

How many days are there in total? ** First, we add the two types of days together to find 10+10=<<10+10=20>>20 days in total between the two types.
How many days are left? ** We then divide this number in half to find Mark's remaining number of days, getting 20/2= <<10=10>>10 days remaining.
How many hours' worth of days does Mark have left? ** Since each day counts as 8 hours, we multiply 10*8= <<10*8=80>>80 hours' worth of days remaining for Mark.
