Suppose that nominal GDP growth is 1.5% and real GDP growth is -7.8%. What is (approximately) the inflation rate? (Submit your answer with up to two decimals, i.e., 10.22 for 10.22% and 11.44 for 11.442%.)

Hint: It may be useful to think of Nominal GDP as being equal to P multiplied by Y, where P is the price index and Y is real GDP.
