Answer:
$14
Step-by-step explanation:
Assuming the cost of folder to be [tex] x [/tex], then the cost of notebook will be [tex] 4 x [/tex] and the cost of set of pencils will be [tex] 2 x [/tex].
Cost of the folder = $2
Cost of notebook = 4 × 2 = $8
Cost of pencil = 2 × 2 = $4
Total cost of 1 folder, 1 notebook and 1 set of pencils = $2 + $8 + $4 = $14
