The cost of mailing a first-class letter is $0.46 for the first ounce and $0.20 for each additional ounce or portion of an ounce. Y is the total cost for mailing a letter that weighs x ounces. Which type of function model would be appropriate for this situation?

If y is the total cost to mail a letter, that is what your equation should be set equal to. 
y = _________
Then, just to be able to send the letter, you have to pay .46 before you even weigh it.
y = 0.46 + _____
Finally, you can weigh your letter to determine how much more you'd have to pay (it wouldn't be fair if a 1 ounce letter and a 5 pound letter costed the same!). The problem gives you the variable for ounces, so you would do
price x ounces.

y = 0.46 + 0.20x
(I'm not sure what the name of the equation is, but it is in y = mx + b form. I believe it is "slope intercept"? That should be somewhere in your notes. Hope this helps :) )

The total cost will be y = 0.46 + 0.20x.

In this case, the intercept slope will be used in solving the question which will be:

y = mx + b

y = 0.20(x) + 0.46

y = 0.46 + 0.20x

In conclusion, the total cost for mailing a letter that weighs x ounces is y = 0.46 + 0.20x
