Hi please help. Thanks and god bless. 

Janice has some blue and green marbles. If she uses 30 blue marbles, the number of blue marbles left will be 20% of the total number of marbles left. If she uses 60 green marbles, the number of blue marbles left will be 25% of the total number of marbles left.

a) How many beads does Janice have altogether? 

B) what fraction of jolene’s marbles are blue?
