My BMI Calculator V2

weight = 70
height = 1.85

bmi = weight / (height ** 2)
print(bmi)

if bmi < 18.5:
    print("Underweight")
elif bmi < 25:
    print("Normal Weight")
else:
    print("Overweight")

# I note that in Angela's example she has the if/elif/else the opposite way around.
# I have not found any errata in my code, the weights appear to be identified correctly 
# if bmi >= 25:
#    print("overweight")
# elif bmi >= 18.5:
#    print("normal weight")
# else:
#    print("Overweight")

My pizza order

    else:

# Calculate the cost of the extra cheese
