There are only red marbles and green marbles in a bag. The ratio of red marbles to green marbles in the bag is 4:7. Julia then adds 90 red marbles and 36 green marbles to the bag, which makes the probability of selecting a red marble from the bag on a random draw equal to . How many total marbles are in the bag after Julia has added the 126 marbles?
