The table below shows Country C's GNI per capita (US$) and annual population‑growth rates. | Year | GNI per capita (US$) | Population‑growth rate (%) | |------|----------------------|----------------------------| | 2015 | 4,500 | 2.0 | | 2016 | 4,620 | 1.9 | | 2017 | 4,750 | 1.8 | | 2018 | 4,880 | 1.7 | | 2019 | 5,020 | 1.6 | The government aims to reach a GNI per capita of 7,000 US$ by 2025. Assuming the per‑capita GNI continues to grow at the average annual rate observed over 2015‑2019, and that population‑growth rates decline linearly by 0.1 % each year after 2019, what average annual growth rate (in % to one decimal place) in **total** GNI is required to meet the 2025 target?
