Write a Python program that asks the user to enter the monthly costs for the following expenses incurred from operating his or her automobile:

1. Loan payment
2. Insurance
3. Gas
4. Oil

Write a function that takes these six items as arguments and computes the total cost of these expenses.

Write a main program that asks the user for these six items and calls your function.

Print total monthly cost and the total annual cost for these expenses.

Your function should not have any input statements or print statements (except for debugging print statements).

5.a. What class of meteorite should have a composition closest to cosmic abundances? Why?

5.b. Most asteroids are C-type, but most meteorites are not carbonaceous chondrites. Why might this be?
