Zax decides to go through with setting up this repair and support service. However, it turns out that some of his estimates above were not accurate:

• The estimated startup cost of $29,000 was correct.
• The first level quarterly payment Zax receives will be exactly 3 months from the start of this service (and not 6 months as Zax estimated).
• However, the level quarterly payment Zax would receive is more likely to be 2769.2875682923.
• These quarterly payments are still expected to only last for 3 years.

Again, ignoring the compensation he is paying to Banner, determine the return Zax is earning on this repair and support service, expressed as a nominal annual rate compounding quarterly. Give your answer as a percentage to 4 decimal places.
