The question asks to calculate the percent of change in the number of candid student pictures in the yearbook from 2007 to 2008. First, we find the absolute increase in the number of pictures by subtracting the 2007 value from the 2008 value. Next, we divide the absolute increase by the 2007 value to find the relative increase. Finally, we convert this relative increase to a percentage by multiplying by 100 and round to the nearest tenth.
Step-by-Step Calculation:
Find the absolute increase: 236 (2008) - 214 (2007) = 22 pictures.
Calculate the relative increase: 22 / 214 ≈ 0.1028.
Multiply by 100 to get percent: 0.1028 × 100 = 10.28%.
Round to the nearest tenth: 10.3% (percent of change).
