Final answer:
After deducting the $200 flat rate from their $1200 budget, the Kubys have $1000 remaining to cover the cost of guests. With a charge of $20 per person, they can invite a maximum of 50 guests to stay within their budget.
Step-by-step explanation:
Patricia and Joe Kuby are planning a 75th wedding anniversary celebration at the Diplomat Party House with a budget of $1200. The party house charges a flat rate of $200 for setup and cleanup. Additionally, there is a charge of $20 per person. To calculate the maximum number of guests, we must first deduct the flat rate from the budget:
- Total budget: $1200
- Flat rate cost: -$200
- Remaining budget for guests: $1200 - $200 = $1000
We then divide the remaining budget by the cost per person to find the maximum number of guests:
- Remaining budget for guests: $1000
- Cost per person: $20
- Maximum number of guests: $1000 ÷ $20 = 50 guests
Therefore, the maximum number of guests that the Kubys can invite and stay within their budget is 50 guests.
