Give the step-by-step reasoning process and then the final answer. John decides to get a new phone number and it ends up being a recycled number. He used to get 20 text messages a day. Now he is getting 55. Assuming the number of texts his friends send has not changed, how many text messages per week is he getting that are not intended for him?
He is getting an extra 55 - 20 = 35 text messages per day. So he is getting an extra 35 * 7 = 245 text messages per week.
The final answer: 245.
