Your local telephone company has offered you a choice between the following billing plans: Plan A: Pay $0.05 per call. Plan B: Pay an initial $2/wk, which allows you up to 30 calls per week at no charge. Any calls over 30/wk cost $0.05 per call. If your income is $12/wk and the composite good costs $1, graph your budget constraints for the composite good and calls under the two plans.
