a binder, a pack of notebooks and a box of pencils cost 14$ the pencils cost twice as much as the binders the pack of notebooks cost two dollars more than the binder how much does each cost

b = binder

n = notebooks

p = pencils

b + n + p = 14

p = 2b

n = b + 2

Substitute => b + (b + 2) + (2b) = 14

4b + 2 = 14 => b = 3, n = 5, p = 6

binders = 3$

pack of notebooks = 5$

box of pencils = 6$
