Recalling the 2011 IRS Mileage Rate Percent Change Calculation

As part of your onboarding training as a travel expense auditor at Apex Logistics, you are asked to demonstrate your recall of historical mileage rate adjustments. From memory of the core training manual's example on the 2011 IRS deductible mileage rate change, write a brief essay that recalls:

  1. The original rate and the new increased rate (in cents per mile) set by the IRS in 2011.
  2. The calculation to find the exact amount of change between these two rates.
  3. The algebraic translation equation set up to solve for the percent change (pp).
  4. The final solved percentage change, rounded to the nearest tenth of a percent.

Ensure you clearly label each part of your mathematical explanation.
