Respuesta :

$24.99 + $12.50m = Cost for Gym Membership
$24.99 + $12.50m = $174.99

              $174.99 = $24.99 + $12.50m
$174.99 - $24.99 = $24.99 - $24.99 - $12.50m
              $150.00 = $12.50m
  $150.00/$12.50 = $12.50m/$12.50
                       12 = m

This membership will last 12 months.
C is the answer and the equation to get that answer is 174.99=24.99 + 12.50m . M=months
