Final answer:
The rate the landlord is charging Ophthalmology is approximately 0.973% per month.
Step-by-step explanation:
To calculate the rate the landlord is charging Ophthalmology, we can use the formula for Present Value of an Annuity. The Present Value of an Annuity is calculated using the formula:
PV = PMT x ((1 - (1 + r)^-n) / r)
In this case, the improvement costs $1.4 million and the payment associated with the improvement is $18,000 monthly for 10 years. By substituting the values into the formula, we can solve for the rate (r) the landlord is charging Ophthalmology.
Let's substitute the given values into the formula:
PV = $1,400,000
PMT = $18,000
n = 10 * 12 = 120 (since there are 12 months in a year)
Now we can solve for r.
By rearranging the formula and solving for r, we find that the rate the landlord is charging Ophthalmology is approximately 0.973% per month.
