An ice cream cone is left sitting in the hot sun. Sarah notices that the ice cream melts and loses half of its volume every 5 minutes. If the starting volume was 125 mL, determine a function for the volume, with respect to the amount of time left out in the sun.

If m is minutes, f(m)=$${\mathtt{125}}{\mathtt{\,\times\,}}{{\mathtt{2}}}^{{\mathtt{\,-\,}}\left({\frac{{\mathtt{m}}}{{\mathtt{5}}}}\right)}$$ . But the question isn't realistic. If ice cream lost half its volume every 5 minutes, the last speck would never disappear completely.
