I have been struggling to answer this question. Little help from you will mean a lot to me! If you can tell me how to solve problem step-by-step, it will be great.

<Price of Soya Beans>

Price in $/tonne (Dec 31) CPI (Jan 1-Dec 31)
Year 5 $359 +1.7%
Year 6 $375 +2.1%

Question: What was the effective increases in the price of Soya beens in Year 6, compared to Year 5, if the CPI had been taken into account?

Thanks a lot.
