Question

The Science Club went on a two-day field trip. The first day the members paid $30 for transportation plus $18 per ticket to the planetarium. The second day they paid $85 for transportation plus $15 per ticket to the geology museum. Write an expression to represent the total cost in dollars for two days for the n members of the club.

Answer 1

1st day $30+$18=$48
2nd day $85+$15=$100

You can do both days separate
$48n+$100n

Or add the days together and multiply the cost by the number of members
$148n
