Answer:
135 + 23n
Step-by-step explanation:
The Science Club went on a 2 day field trip.
The first day the members paid $40 for transportation plus $13 per ticket to the planetarium:
40 + 13n
The second day they paid $95 for transportation plus $10 per ticket to the geology museum:
95 + 10n
Therefore, total cost for 2 days (sum both expressions)
40 + 13n + 95 + 10n = 135 + 23n
