**QUESTION 1**

1.1

Audrey started a stokvel on 1 February 2015 to save for the December holidays. She invited 21 friends to join the stokvel. The aim was to continue with the stokvel after 2015.

Guidelines for this stokvel:

- A bank account should be opened and all monies collected should be deposited on the 7 of every month.
- The initial fee to join the stokvel is R250 per member. This initial fee is non-refundable and will be used to continue the stok vel in the future.
- The monthly contribution of each member is R400 and is payable on the 1
^{st}day of every month. - Members who pay after the 7
^{th}of a month have to pay a fine of 4,75% of the monthly contribution, in addition to the monthly contribution. - On 20 December 2015 each member will be paid an equal amount of the savings in the account, excluding the initial fees to join, which will be kept in the stokvel account.

During the first meeting all the members paid their initial fees and their first monthly contributions.
