Question

From Monday through Friday, James works in the library on 2 days and in the cafeteria on another day. On Saturday and Sunday, James washes cars 50% of the days. How many days does James work in a week? What percent of the days from Monday through Friday does he work?

Answer 1

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:

$\dfrac{3Days}{5Days}$

$\dfrac{3Days}{5Days}=0.6$

Now to find the percentage, we multiply the total to 100.

0.6 x 100 = 60%
