Question

The cost in dollars of a field trip is 64 +14n, where n is the number of people attending. What is the cost for 48 people?

Answer 1

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`
