Assume that the regression line for the New York City murder rate per 100,000 residents between 2000 and 2010 is given by y=−0.24x+488.7, where x is the year and y is the murder rate. Interpolate to get an approximate value for the rate in 2006. Round your answer to one decimal place.

1.We all regularly enter into contracts during our daily routines, even though most of us do so without even thinking about it. Describe three contracts, either express or implied, that you have entered into in the past month. In doing so, describe the offer and acceptance, and the consideration given by each party.
2.During a capital improvement funding drive at her church, Betty pledged to give $40,000 toward a new church steeple. In response to Betty's pledge, the church entered into a contract with a private company for the creation and purchase of the steeple. Once the company completed the steeple, they sent an invoice to the church with a purchase price of $55,000. The church then contacted Betty and asked for her $40,000 check. Reluctantly Betty told the church that due to some unforeseen medical bills, she could no longer donate the $40,000.
Did Betty and the church have a legally enforceable contract for the $40,000 donation? Why or why not? Is there any way that the church can force Betty to pay, regardless of whether or not there was a legal contract?
