The rate of unionization in the economy can be calculated by dividing the total union membership by the total number of workers and multiplying by 100: 
(30 million/100 million) x 100 = 30%

The rate of unionization in retail trade can be calculated by dividing the number of unionized retail workers by the total number of retail workers and multiplying by 100:
(2 million/8 million) x 100 = 25%

Therefore, the correct answer is C: 30 percent, and the rate of unionization in retail trade is 25 percent.
