# Question #bc6a4

##### 1 Answer

36 marbles

#### Explanation:

So let's list our marbles:

B = 50%

G = 30%

R = 6

Out of 100%, if B is 50% and G is 30%, then that must mean R is 20%. Now that we know that 6 is 20% out of 100%, we can find out the total of marbles we have.

If 6 is 20%, then we multiply it by 5 to find out the total marbles.

So let's find out the number of blue and green marbles. For blue, 50% of 30 is 15 marbles. For green, 30% of 30 is 9 marbles.

The question asked to increase the blue marbles by 40%. So 40% of 15 is 6. Then we add this 6 to our blue marbles.

40% of 15 =

Let's relist our marbles:

B = 21

G = 9

R = 6

Now, all that's left is to add them all to get our total marbles.
