With its new global mobile phone service, Ultra Mobile offers the following price schedule: • Your first 10 minutes each day cost 25 cents per minute • All minutes after that are just 10 cents per minute • There are no additional charges, and no contract to sign or fixed monthly fees. If Peter's demand for global phone minutes is P = 20 -4Q, where P is in cents per minute and Q is in minutes per day, what is Peter's daily consumer surplus? O 2.5 O 12.5 O 25 O 50
