The revenue R from selling x number of phone widgets is given by $\displaystyle {R}={22}{x}$, and the cost C of producing those widgets is given by $\displaystyle {C}={11}{x}+{2816}$. Find the number of widgets it requires to break even.

It requires widgets to break even (NO COMMAS).

It would cost $ dollars to produce that many widgets (NO COMMAS).

Hint: The break even point is when $\displaystyle {R}={C}$
