The following table provides details of the postage rates for different weights of packages. In my capacity as Secretary of the Black Knight Chess Club I am about to send minutes of the last meeting to each of the eight other members of the Committee. The weight of each envelope, including its contents, is 70 g. Three of the members are new to the committee and I intend to include with their minutes a copy of our constitution, which weighs 40 g. What will be the cost of sending these items second class?
