Question 1018888
Name the variables.
{{{O}}}-Old plan cost per month
{{{N}}}-New plan cost per month
So,
{{{N=O-3.50}}}
There are 12 months in one year,
{{{12N=294}}}
So then,
{{{N=294/12}}}
{{{N=24.50}}}
Substituting into the equation,
{{{24.50=O-3.50}}}
{{{O=28.00}}}
She paid $28 a month on the old plan.
