  1. It looks like he pays 2.10/6 = $0.35 per additional minute, plus a single connection charge (which usually covers the first one or three minutes).

    You don't need to know the connection charge to solve this.

    30 minutes is an additional 20 beyond a 10 minute call, and would cost 20x0.35 = $7.00 more, or %11.75.
