How many ways can six friends be arranged around a circular dinner table?

1 answer:

6 0

A question such as this one is a little tricky since the people seated are not in a straight line.

For a circular table seating question, (n-1)! formula is used. Without restrictions 5! people can be seated.

You might be wondering why it is not 6!, this is because the first person will the the 6 person so you are accounting for the same person twice.

Hope I helped :)

A lawn service charges $30, plus $15 per hour. If X represents the number of hours, then the expressions for the total charge is

It's going to be the first one...

How you solve this is just insert the number of hours you want for X then solve the equation.

15 * 1 = 15

15 + 30 = 45

15 * 3 =45

45 + 30 = 75
