Using the notation Pt to designate this period's price level and Pt-1 to designate last period's price level, the formula for measuring the inflation rate from last period to this period is A: [(Pt - Pt - 1) / Pt] × 100. B: [(Pt -1 - Pt) / Pt - 1] × 100. C: [(Pt - Pt - 1) / Pt - 1] × 100. D: [(Pt -1 - Pt) / Pt] × 100.
