Hey everyone, I am doing the Python Syntax: Medical Insurance Project and when I print to the terminal I’m not getting the correct math.

**Heres my code:**

**# create the initial variables below**

age = 28

sex = 0

bmi = 26.2

num_of_children = 3

smoker = 0

**# Add insurance estimate formula below**

insurance_cost = 250 * age - 128 * sex + 370 * bmi + 425 * num_of_children + 24000 * smoker - 12500

print(“This person’s insurance cost is " + str(insurance_cost) + " dollars.”)

print("")

**# Age Factor**

age += 4

new_insurance_cost = 250 * age - 128 * sex + 370 * bmi + 425 * num_of_children + 24000 * smoker - 12500

change_in_insurance_cost = new_insurance_cost - insurance_cost

print(“The change in cost of insurance after increasing the age by 4 years is " + str(change_in_insurance_cost) + " dollars.”)

print("")

**# BMI Factor**

age = 28

bmi += 3.1

new_insurace_cost = 250 * age - 128 * sex + 370 * bmi + 425 * num_of_children + 24000 * smoker - 12500

change_in_insurance_cost = new_insurance_cost-insurance_cost

print(“The change in estimated insurance cost after increasing BMI by 3.1 is " + str(change_in_insurance_cost) + " dollars.”)

**Here is what the terminal prints**

This person’s insurance cost is 5469.0 dollars.

The change in cost of insurance after increasing the age by 4 years is 1000.0 dollars.

The change in estimated insurance cost after increasing BMI by 3.1 is 1000.0 dollars.

If I did my math right, and I think I did it should not be a 1000 dollar difference each time. I’ve checked my code several times and cant figure out what I’ve done wrong.

Thanks for the help
