Please answer and explain it in detail. Thank you!

An insurance company is setting up a way to evaluate the monthly premium of a medical insurance for doctors.
To obtain a more accurate model, they want to set it up as a differential equation with:
• Output: I = the price of the medical insurance in Canadian dollars
• Input y = the number of years a doctor has been in service
Their model must satisfy the following requirements:
1. The price I should increase proportionally to the number of misdiagnoses M and inversely proportionally to the doctor's experience - with one
proportionality constant for both;
2. The number of misdiagnoses M is modelled by the square root of the years the doctor has been in service;
3. A doctor's experience is given by the difference between the square of the years the doctor has been in service and the number of missed
diagnoses;
4. When a doctor reaches 4 misdiagnoses, then the insurance price should be set as CAD$ 1890.
To help the insurance company, set up a differential equation that satisfies the requirements above:
dI
dy
Hint: Your answer should depend only on y and I.
The insurance company people know enough about differential equations to understand that a differential equation has infinitely many solutions, so they
also need you to give them an "initial condition":
