You want to work four days a week.
How many ways can you schedule your four-day work week?

To determine how many ways you can schedule your four-day work week, we need to calculate how many unique combinations of 4 days can be selected from the 7 available days in a week.

This is a combination problem since the order of the days does not matter. The formula for combinations is given by:

\[
\binom{n}{k} = \frac{n!}{k!(n-k)!}
\]

Where:
- \(n\) is the total number of days in a week (7),
- \(k\) is the number of workdays you choose (4).

Thus, the number of ways to schedule your workweek is:

\[
\binom{7}{4} = \frac{7!}{4!(7-4)!} = \frac{7!}{4!3!}
\]

Now, let's calculate that.

\[
\binom{7}{4} = \frac{7 \times 6 \times 5 \times 4!}{4! \times 3 \times 2 \times 1} = \frac{7 \times 6 \times 5}{3 \times 2 \times 1} = \frac{210}{6} = 35
\]

Therefore, there are 35 different ways to schedule your four-day work week.
