26 Buying your first car

27 Number yourselves 1 to 4… In charge of reading the introduction to the group, and is also the only person that needs a calculator. In charge of writing the plan on a separate sheet of paper. In charge of completing the poster that will be displayed. Time keeper, only person in the group that can ask the teacher a question. **If you are in a group of 3, combine roles 1 and 4 (so you will have a Person 2, a Person 3, and a Person 1/4).

28 So about that car………

29 Let’s start with Scenario Two:
If the $17,000 car depreciates at a rate of $150 per month, find the value of the car after 2 years. a) Create a NEXT-NOW statement that will represent the scenario START = 17000 NEXT = NOW – 150

30 START = 17000 NEXT = NOW – 150 Use a calculator to find the value of the 24th month. This is called an iteration (repetition of a process) $13,400

31 RECURSIVE FORMULA We can also represent this scenario using a
(uses the previous term to find the next term) To set up a recursive formula, let us look at some important notation. When referring to a specific term, like the initial term, we can represent it with an a0

32 For example, if we have the sequence 3, 7, 11, 15, …
We would say a1 = 3 And a2 = 7 What would a5 = ? 19 What’s the difference between a0 and a1? a0 refers to an initial term, whereas a1 refers to the first term of a sequence.

33 So let’s write START = 17000 NEXT = NOW – 150 a0
The notation an refers to a general sequence. n is considered the term number (must be a whole number) For example, an = 9, 2, -5, -12, … So let’s write START = 17000 NEXT = NOW – 150 using our new notation a0 an an-1

34 3. Write the first 4 terms of the sequence below:
Write the following sequences using a NEXT NOW statement AND write as a recursive formula 1. an = 10, 20, 30, 40, … a1 = 10 an = an START = 10 NEXT = NOW + 10 2. an = 2, 4, 8, 16, … a1 = 2 an = 2an-1 START = 2 NEXT = 2NOW 3. Write the first 4 terms of the sequence below: a1 = 2 an = an-1 – 6 2, -4, -10, -16

35 Let’s go back to the car…Scenario One
The $17,000 car depreciates at 0.9% per month What is challenging about this problem is we need to focus on how much the car is WORTH each month, not how much value the car lost each month.

36 Write a NEXT NOW statement and recursive formula for this scenario.
So…the car’s value is 99.1% of it’s previous amount. We also must keep in mind the value of the car each month is dependent of the previous month. Write a NEXT NOW statement and recursive formula for this scenario. START = 17000 NEXT = 0.991NOW a0 = 17000 an = 0.991an-1

37 Use your calculator to find the value of the car after 24 months.
$13,684.11

38 How do you find the amount owed on the loan?
$17,000 with an interest rate of 2% per month, but you pay $500 a month Start = 17,000 Next = 1.02Now - 500 Amount owed on the loan: $12,132.50 Recursive Form a0 = 17000 an = 1.02an-1 – 500

39 Equity? (Car value – amount remaining on loan)
Scenario 1: $1,551.61 Scenario 2: $1,267.50

40 Practice with Recursive Formula
Do numbers 1, 2, 4, and 6

41 Homework Day 1 Homework – Introduction to Sequences Worksheet
