Problem:

John’s electronic piggy bank gives him a reading of how much money he puts in. Today he notices something strange when he puts money in. When he puts in 10 cents, the bank reports 23 cents; when he puts in 25 cents, the bank reports 53 cents; and when he puts in 32 cents, the bank reports 67 cents. Complete the Money In/Report Out table below to help you find out how much money the piggy bank would report if John deposits 45 cents. Explain how you found your answer.
