4. mail it cost ramon $3.73 to mail a package to his grandmother. the post
office charged $2.38 for the first pound and 45 cents for each additional
pound. how much did the package weigh?

4 pounds

Step-by-step explanation:

First, I subtracted the cost of the first pound from the final product (3.73 - 2.38) and I got 1.35. I then divided the 1.35 by .45 (the 45 cents) to figure out how many more pounds the package was from the initial 1 pounds. 1.35/.45 is 3, plus the 1 pound from the beginning makes 4 pounds in total.
