Answer:

a. 15 Jellybeans.

Step-by-step explanation:

Jackie began her day with a pocketful of jelly beans (we will call the jelly beans X incognita).

She gave half of them to her friend Marcus ( So, she now have 1/2X or 3/6X)

and then a third of what she had left to Shelby (a third of the half left: (1/2 - 1/3)X=1/6X is what she gave to Shelby from the starting amount).

Finally, she and her sister each ate five jellybeans and no jellybeans remained( this means, 10 jelly beans represent two-sixth of the initial amount of JB half: 10= 2/6X)

How many jellybeans did she give to Marcus?

If you use that last equation

10= (2/6)X

And clear the X

X= 30 jelly beans

That's the starting amount. Marcus recibed half of it, so he has 15 jelly beans.

Answer:

a. 15 Jellybeans.

Step-by-step explanation:

Let "a pocketful of jelly beans" = x jelly beans.

"She gave half of them to her friend Marcus"

Now she has x/2 jelly beans left.

"and then a third of what she had left to Shelby"

If she gives away 1/3 of an amount, she has left 2/3 of the amount.

Now she has (2/3)(x/2) = x/3

She now has 1/3 of the original amount.

"Finally, she and her sister each ate five jellybeans and no jellybeans remained."

They ate a total of 10 jelly beans, and none were left.

The amount remaining, x/3 was 10.

x/3 = 10

Multiply both sides by 3:

x = 30

She started with 30 jellybeans.

"She gave half of them to her friend Marcus"

30/2 = 15

Answer: a. 15 Jellybeans
