18 jellybeans
a. 15 jellybeans.
b. 12 jellybeans
c. 24 jellybeans
d. 24 jellybeans.

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

a. 15 Jellybeans

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7
