'''Sampla'''
Le feidhm mheánioncaim líneach <math>p(X) = a – bX</math>
agus costais imeallaigh seasmhacha <math>c'(X) = c</math> *<math> \pi(X) = p(X)X – c(X)</math>
*<math> \pi(X) = (a - bX)X - cX</math>
Line 33 ⟶ 34:
*<math>X = \frac{a - c}{2b}</math>
an t-aschur a tháirgfidh an gnólacht i gcothromaíocht
*<math>p = \frac{a + c}{2}</math>
an praghas a ghearrfar ar an aschur seo
*<math>\pi = \frac{a - c}^2{4b}
