For her parents' anniversary party, Scarlett is considering using one of two venues. A hotel in
Salem will cost $50 for a reservation, plus $8 per person. A restaurant in the same city will
cost $4 per person, in addition to $70 for the reservation. In order to make the best decision,
Scarlett figures out how many attendees it would take to have the venues cost the same
amount. How many attendees would that be?
