**12/14 Bell Ringer – ON NB PAPER**• Santos just got $1,000 for Christmas and wants to save it for 7 years. He has 2 choices for his money. Your job is to determine which choice he should make: • Invest in a CD that earns 6% annually, compounded monthly. • OR • Invest in a mutual fund that earns 7% annually, compounded annually. This is another good chance to gauge your progress and preparation for the test TOMORROW! Take 7 minutes to complete as much as you can! Hints are timed every 2 minutes 2 Minute Hint: Must convert 6% and 7 years to monthly rates (.06/12 and 7*12) 4 Minute Hint: A = 1,000(1.005)84 and A = 1,000(1.07)7 (If you’re done, go on to continuous and figure out each if interest was compounded continuously). 6 Minute Hint: Which investment will have more money after 7 years?**12/14 News and Notes**• TEST TOMORROW! • REVIEW PACKETS WILL BE HANDED IN TOMORROW**Today’s Goal: Use 46 Minutes Wisely to Prepare for Test**• You are either: • 1.
