The group members each posted 50 messages in a day, a total of 50 * 130 = 6500 messages. In a week, with seven days, the group members would have posted 6500 * 7 = 45500 messages. Final answer: 45500. <ibo> Ọ bụrụ na e nwere ndị otu 150 n'otu ahụ tupu onye nchịkwa ewepụ 20, mgbe ahụ 150 - 20 = 130 ndị otu fọdụrụ mgbe ewepụrụ 20.
