Assume it costs 30 cents to mail a letter weighing one ounce or less, and then 28 cents for each additional ounce or fraction of an ounce. Write a piecewise-defined function P(x) that represents the cost, in cents, of mailing a letter weighing between 0 and 3 ounces.

Step-by-step explanation:
We are given the following in the question:
Cost of sending a mail =
30 cents for 1 ounce or less.
28 cents for each additional ounce or fraction of an ounce.
Let x represent the weight of mail. Let P(x) represents the cost in cents.
Weight of mail between 0 and 1 ounces
Weight of mail between 1 and 2 ounces
Weight of mail between 2 and 3 ounces
Thus, we can write the piecewise function for cost in the following manner:
where x is in ounces and P(x) is the cost in cents.
