Final answer:
The price as a function of the number of travelers is $4000 - ($20 * (number of travelers - 30)), and the revenue as a function of the number of travelers is Price * Number of travelers.
Step-by-step explanation:
In this question, we are given a package price of $4000 per person if there are 30 or fewer people. For each additional person, the price is reduced by $20 per traveler.
To find the price as a function of the number of travelers, we can use the formula:
Price = $4000 - ($20 * (number of travelers - 30))
For example, if there are 35 people, the price would be $4000 - ($20 * (35 - 30)) = $4000 - $100 = $3900.
To find the revenue as a function of the number of travelers, we can use the formula:
Revenue = Price * Number of travelers
For example, if there are 35 people and the price is $3900, the revenue would be $3900 * 35 = $136,500.
