Answer:
Part A
The costs consist of one off payment to get the cottage ready and daily utility charges:
- C = 400 + 15x
Part B
The revenue is the sum of daily rental:
- R = 115x
Part C
To solve it as a system we make C= R or:
- 400 + 15x = 115x
Solving we get:
- 400 = 115x - 15x
- 400 = 100x
- x = 400/100
- x = 4
It gives us:
- C = 400 + 15*4 = 460
- R = 115*4 = 460
The meaning of the solution is the number of nights we can pay off the costs and after 4 days we start to get profit.
