use the future value formula to find i

Please proofread your post.....

 

I think it is supposed to be 4217 = 600 (1+i)⁶   - 1/i    ??

4217 = 600 (1+i)6   - 1/i        Divide through by 600

7.02833 = (1+i)^6  - 1/i

 

I am not sure how to complete this except graphically......where I get   i = .449     or  44.9 %  

 

Here is a desmos graph:
