A person buys a phone for $89 and signs up for a single-line phone plan with 2000 monthly anytime minutes. The plan costs $116.95 per month. Write an equation that can be used to determine the total cost, C(t), of this phone plan for t months. Then, find the cost for 24 months, assuming that the number of minutes the person uses does not exceed 2000 per month.
