Answer: 3 cases
Explanation:
The entrepreneur charges $335 per case but members of the Wine Appreciation club can buy the cases for $200 if they pay an annual fee of $300.
The saving made by the members of the club is:
= 335 - 200
= $135 per case
Considering that they spend $300 on fees, the amount of cases that would give them a savings of more than this amount is:
= 300 / 135
= 2.22 cases
= 3 cases (rounded up)
At 3 cases they would make savings of:
= 3 * 135
= $405
This is more than the fee paid.
