Question

a ceramic tile designer has some odd lots of tiles in boxes. a particular box contains square, pentagon and hexagonal tiles. altogether there are 100 tiles. there are 20 more pentagonal tiles than hexagonal tiles in the box.

Answer 1

So far, you've got:

s + p + h = 100

and,

p = h + p

So, you have three unknowns and just two equations. You can't solve this yet...
