To calculate the unweighted aggregate price index, the sum of the prices in each year is divided by the sum of the base year prices and multiplied by 100. In this case, the sum of the prices in 2010 is $32 + $52 + $25 = $109. Dividing by the sum of the base year prices ($25 + $45 + $20) and multiplying by 100 gives an answer of 109.388. Therefore, the correct answer is C.
