To determine if Alice can stay within the $800 budget for the picnic, we need to calculate the total cost based on her plan to invite 30 people for a 4-hour picnic.
-
Entrance Fee for 30 People:
The park charges $20 per person.
Total entrance cost = 30 people × $20/person = $600. -
Pavilion Rental for 4 Hours:
The park charges $50 per hour for the pavilion.
Total pavilion cost = 4 hours × $50/hour = $200. -
Total Cost:
Total cost = Entrance cost + Pavilion cost
Total cost = $600 + $200 = $800.
Since the total cost of $800 exactly matches the budget, Alice can stay within the budget with her plan.
Thus, the correct response is:
Solving an equation representing this situation proves that 30 people for exactly a 4-hour picnic is possible within the $800 budget.
