Answer:

The cost for 48 people is $672.

Explanation:

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#
