           Bargain Membership (6 years for the price of 5 @ $100) 
                                                      I am unsure 
                                       Lifetime Membership ($300) 
                                            Not yet retired ($10) 
                                                Out-of-area ($10) 
Out-of-area Bargain Membership (6 years for the price of 5 @ $50) 

I add these 7 numbers together, which gives me 740. But in my R studio, it says I have 782 observations. Why?

Table doesn't show Nas by default. Check the documentation for the NA options

How to show those NAs? I also want to include those NAs in my table.

In general you access documentation by questionmark function name in the console.
