Carrie is planning her birthday party at a restaurant. She cannot spend more than $75 on the party. The cost per person for the meal is $12. There is also a $10 charge for the room. The number of friends, f, that Carrie can invite is represented by the inequality 12f + 10 < 75. How many friends can Carrie can invite to the party if her budget is $75 or less?
Your budget minus The room is $65, now if its $12per person to come and your including yourself in the the number, then $12x5=$60 and now your out of money, so the answer is 5.
