Suppose the government officials use the percentage of the GDP deflator to measure how fast the aggregate price level is changing over time. According to the country's statistics department, the nominal GDP in year 1 and year 2 are $1,250 and $1,345 respectively; while the real GDP in year 1 and year 2 are $1,265 and $1,398 respectively. Find the percentage change in the aggregate price level from year 1 to year 2.

Note: Keep you answer in percentage terms and rounded to 2 decimal places. For example, if your answer is 12.34%, then enter 12.34 in the answer box. You do not need information on which year is the base year, it is not relevant here.
