Question

Help my little sister

Answer 1

If the folder cost $2 and the notebook cost 4 times that then the notebook cost $8

If the notebook cost 2 times the cost of a set of pencils and a notebook cost $8 then a set of pencils cost $4 (half the cost of the notebook)

We already know the cost of the folder is $2 and we need one of each idem: Folder=$2  Notebook=$8  Pencils=$4 

2+8+4
10+4
14

The total is $14

Answer 2

The total cost of 1 folder, 1 notebook, and 1 set of pencils is $14.00 because 8 + 2 + 4 = 14.
