Answer:
We can invite at most 80 people without going over our budget.
Explanation:
The available budget is $ 2,100.
As a fixed amount we must pay $ 95 for the cleaning service. After making this payment we would be available $ 2,100 - $ 95 = $ 2,005 to cover the food and drink expenses of the guests. Since for each guest they charge us $ 25, we can invite a maximum of 80 guests ($ 2,005 / $ 25 = 80.2). Considering that we will invite 80 people, the total cost of the event will be $ 95 + 80. $ 25 = $ 2,095, that is, we will finally have $ 5 left over.
