I am solving the following problem:
The owner has premises that he decided to rent. Rental costs for the first year are 1000 and each year costs increase by 5% for 5 years.
How much rent should be agreed with the customer to cover all costs?
My solution:
I calculated the price of the rent during following 5 years:
year: 1000
year:1050
- year:1102,5
- year:1157,625
- year:1215,51
Then I added the numbers and then discounted it for five years:
$$\frac{5525,635}{\left ( 1+0,05 \right )^{5}}$$
Is that correct?
