Answer:
4
60%
Step-by-step explanation:
To find how many days James works in the week we first need to analyze the problem.
Monday to Friday = 5 days
On 2 days he works in a library.
On another day he works in the cafeteria.
So that means that James works.
2 days Library + 1 day Cafeteria = 3 days.
Now on Saturday and Sunday James works 50% of the days.
Saturday and Sunday = 2 days
50% of 2 = 1
So James works 1 day on Saturday and Sundays.
How many days does James work in the week?
Weekdays = 3
Weekend = 1
So James works 4 days in a week.
What percent of the days from Monday through Friday does he work?
James works 3 days of Monday through Friday
Since there are a total of 5 days from Monday through Friday, we can express it like this:
[tex]\dfrac{3Days}{5Days}[/tex]
[tex]\dfrac{3Days}{5Days}=0.6[/tex]
Now to find the percentage, we multiply the total to 100.
0.6 x 100 = 60%
