Calculate the number of days off allowed to pass a 48-week course with 12 hours of class per week, given that attendance must be at least 80%.

How many days can one have off?

Answer :

If you would like to know how many days, weeks can one have off, you can calculate this using the following steps:

48 week course * 12 hours a week = 48 * 12 = 576 hours in total

80% of the class = 80% of 576 hours = 80% * 576 = 80/100 * 576 = 460.8 hours

576 hours in total - 460.8 hours = 576 - 460.8 = 115.2 hours

115.2 hours / 12 hours a week = 115.2 / 12 = 9.6 weeks

You can have 9.6 weeks off.
