a slightly simplified problem - because real life is too complicated

be wary of units

students could total up the cost of the rails plus the posts
this site (for example) could be used

you might want to include galvanised nails
and maybe a delivery cost

you might also ask them to create an approximate cost formula, for 'n' meters of perimeter
