Assume 35 MPG and $3.00 gas. Not sure how to figure cost of additional calories expended during biking.

Let's say you burn an extra 500 calories riding a bike an hour and go 35 miles. A candy bar is about as close to pure calories as you can get. So if you spend $1.50 to get 500 calories that means you have gone 35 miles on $1.50 of "fuel". Riding the car would cost $3.00 of gas to go 35 miles. Right?

Do you mean in calories or in dollars? If you assume that you can take your bike anywhere, biking is definitely the cheapest. Calories used when riding a bike will typically not cost you anything extra, they are the same calories that would find a place around your waist if driving a car. A bike will also cost much less than a car to buy.
The only economical aspect left that could possibly make riding a bike more expensive is "Time is money". In other words, if you're so well paid at work that the extra time it takes to get to/from work when riding a bike makes you lose more money from your wage than the gas would cost you.

I read recently that only about 10% of the gas used in a car is needed to move the people. The rest is used for tire friction, wind resistance, lost heat, accessories and braking, etc.; because the car is so heavy. Your numbers look reasonable and you make a good point perhaps that bicycles are more efficient than cars because of reduced weight. Sustaining a speed of 35 mph is more than most people are willing to do for an hour at a time. Also cars allow you to take along a lot of stuff in the trunk (and other people too). The bicycle is not apt to replace the family car soon but it certainly would help folks lose a little more weight, right?

Driving a car cost more because it uses gasoline. But during biking you spend less money on food to give you the energy needed. And it's good for your health as well. The more you execise the healthier your body gets. The less you get sick the lesser you spend on medicine.

Well obviously drive because you don't have the pay for gas when you ride your bike. Also, you get to burn calories!

It costs more money to drive of course! You can't compare money and calories. They aren't compatible. Ever heard of comparing apples and oranges? yeah....doesn't work.
