Human: If the normal hours of operation of Jean's business are 4 pm to 10p every day Monday through Friday, and from 6 pm to 10 pm on weekends, how many hours is the business open in a week? Assistant:
First, we find the number of hours per weekday by subtracting the smaller number time from the larger one, finding 10-4= 6 hours per weekday.
As there are 5 weekdays, this means the business is open 6*5=30 hours a week on the weekdays.
Then we find out the amount of time the business is open on a weekend day, using the same process as we did with the weekdays, finding Jean's business is open 10-6= 4 hours each weekend day.
Since there are two weekend days, this means they are open 4*2=8 hours on the weekends.
We add these two totals together to find that 30+8= 38 hours per week.
