Of 120 hotel rooms rented one night, some were suites rented for $115 each and the rest were double rooms rented for $85 each. If the total revenue from the room rentals for this night was $10,890, how many suites were rented?
Of 120 hotel rooms rented one night, some were suites rented for $115 each and the rest were double rooms rented for $85 each. If the total revenue from the room rentals for this night was $10,890, how many suites were rented?
Let the number of suites rented = S
The number of double rooms rented =120 - S
115S + 85[120 - S] =10,890, solve for S
S = 23 Suites rented
120 - 23 =97 double rooms rented
