The cost for 48 people is $672.

The formula for the cost of the field trip is:

$c = $64 + $14color(red)(n)$

Where $color(red)(n)$ is the number of people attending the field trip.

If we know the number of people, or $color(red)(n)$ , is $color(red)(48)$ we can substitute this into the formula to find the cost.

$c = $64 + ($14 xx color(red)(48))$

$c = $64 + $672$

$c = $672$
