Flatbed drivers showed an 8% increase in seatbelt usage from 2010 to 2013, reaching what percentage?

To understand why the correct answer is 82%, it's important to contextualize the 8% increase in seatbelt usage among flatbed drivers over the specified period. When we assess percentage increases, we start with an initial value and then apply the increase to find the new total.

If we assume that the original percentage of seatbelt usage in 2010 was 74%, the increase of 8% would bring the total up to 82%. This calculation is derived from adding the increase directly to the initial value (74% + 8% = 82%). This demonstrates how percentage increases can impact overall statistics and reflects improvements in safety practices among flatbed drivers over that timeframe.

The other provided choices represent different potential starting values and percentages, but only 82% accurately reflects an 8% increase from a reasonable initial value of seatbelt usage, confirming it as the correct answer.
