Same content across multiple pages

This might be a really simple question, so apologies for my ignorance, but is there a way to have the same text, or pricing table which can be inserted to multiple wordpress pages?

Currently we have our pricing on 3 or 4 pages, and when they change, we have to update all of them.

Furthermore, we want to display our terms and conditions of booking across multiple pages and it would be nice and easy if we could edit the text in the backend in one area, and have it update in multiple places on the site.

Any help on this would be appreciated,

Mike
