Question

A certain mailing service's first class mail rates are $0.37 for the first ounce and $0.11 for each additional ounce or fraction thereof up to 3.5 ounces. A model for the cost C (in dollars) of a first class mailing that weighs x ounces is given below.

C(x) =

0.37 0 ≤ x ≤ 1

0.48 1 < x ≤ 2

0.59 2 < x ≤ 3

0.7 3 < x ≤ 3.5

A.) At what values is the function not continuous?

B.) Find the cost of mailing a 1.6-ounce letter.
