Question
You are mailing a package that weighs 5 pounds, and sending it first class. The post office charges 0.20 for each additional ounce. How much is the total cost to mail this package?
Solution
First, we need to convert the weight of the package from pounds to ounces, since the cost is calculated based on ounces. There are 16 ounces in a pound, so a 5 pound package is 5 * 16 = 80 ounces.
The cost for the first ounce is $0.44. So we subtract 1 from the total ounces to find out how many additional ounces we have. That's 80 - 1 = 79 ounces.
The cost for these additional ounces is 0.20 = $15.80.
Finally, we add the cost for the first ounce to the cost for the additional ounces to find the total cost. That's 15.80 = $16.24.
So, the total cost to mail the package is $16.24.
