Question 1195975

let the nuber of a months be {{{ x}}}

if a high-speed internet service Time Warner Cable offers free installation and costs ${{{42.95 }}} a month  we have

{{{ y=42.95x}}}

if Cincinnati Bell charges a ${{{60}}} installation fee and it cost them ${{{ 24.50 }}} we have

{{{ y=24.50x+60}}}

to calculate a month after how many months will the cost be the same algebra make equations above equal

{{{  42.95x=24.50x+60}}}

{{{  42.95x-24.50x=60}}}

{{{  18.45x=60}}}

{{{  x=60/18.45}}}

{{{  x=3.25203}}}

{{{  x=3.3}}}



 the cost be the same in {{{  3}}}  months and  {{{  9}}} days
