Answer:
The Answers are:
In February, Thorton should charge $6,760
In August, Thorton should charge $11,800
Explanation:
Before I take the solutions for each individual month (February and August), We are going to identify the costs used to run each of the camp site for each month, because this will form the base cost which will be added to the amount earned per camper. These costs include:
1. rental payment per month
2. variable service cost of $6 per camper, and the total cost here is multiplying this amount ($6) by the total number of campers.
After this, we will multiply the amount earned per camper by the number of campers for to get the total amount on all campers for that month.
Finally The total amount earned on the monthly campers are added to the base costs described above.
Now, Let me take the solution of each  month one after the other.
February (330 campers)
1. Rental cost per month = $2,800
2. Total variable service cost on campers = 6 × 330 campers = $1,980
3. Total amount earned on the campers = 6 × 330 = $1,980
Amount to be charged on the land in February = $2,800 + $1,980 + $1,980 = $6,760
For the month of August (750 campers)
1. Rental cost per month = $2,800
2. Total variable service cost on campers = 6 × 750 campers = $4,500
3. Total amount earned on the campers = 6 × 750 = $4,500
Amount to be charged on the land in August = $2,800 + $4,500 + $4,500 = $11,800
