Why the coercion on total due?
Just wondering why the total_due is coerced into a float. I get for number_of_people there can't be 3.5 people thus it's coerced into an integer but why for total_due? Is it because there's a chance the number might be a float?

I would say the string is converted into a number. "Coerced" would typically describe the implicit process that occurs when you perform an operation on different types.
And the value can be expected to represent dollars and cents, so a float is necessary to convert and store it correctly.
