Hi! My name is Lilly. I’m in my last year of high school….so my grad is coming up soon. I’m hoping that you can help me solve a few problems that I have. Hi! My name is Lilly. I’m in my last year of high school….so my grad is coming up soon. I’m hoping that you can help me solve a few problems that I have.

This year we have 150 grads . In the past few years only 48% wanted a theme and 52% didn’t. How Confident can I & the grad committee be that this year will be different?

[object Object],[object Object],[object Object],=Standard deviation Formulas µ=np = √npq

[object Object],[object Object],Mean µ= np=150(0.48)=72 nq=150(0.52)=78 Margin Of Error 6.1188 × 1.96 = 11.99 Finding the 95% Confidence 72 + 11.99 = 83.99 ≈ 64 Max. 72 – 11.99 = 60.01 Min. (84, 60) grads want a theme = √150(0.48)(0.52) = 6.1188

At my school we have only one night to buy our grad dinner & dance tickets. It’s going to take place tomorrow in the gym, after school from 3:30-6:00 then 7:30-9:00.

How many people Grads- 150 Dates/Guests – 100 Parents- 75 ,[object Object],[object Object],[object Object],[object Object],$ 40 × 75 = $ 3,000 Total from parents $ 3,000 Total Profit $17,500 + 3,000 = $ 20,500

Compare the difference if all the tickets were sold. 500 tickets in total. ,[object Object],[object Object],[object Object],250 × 70 = $ 17,500 250 × 40 = $ 10,000 Total amount 17,500 + 10,000 = $ 27,500 Finding the difference 27,500 – 20,500 = $ 7,000

With the grad dinner coming up soon we get to choose who we want to sit with. ,[object Object],So of course I would love to sit with my friends but….we kind of have a problem !

So I’m wondering how many different ways can my friends & I sit? Before we find out we need to know what the formula is & what they mean. Formula n! (n-r)! r! Meanings n = the number of objects that are available to be arranged r = the number of objects that are being arranged. ! = symbol used for factorial notation

The Answer Is……. ,[object Object],There is 12, 870 different ways that my friend & I can sit at the dinner.

[object Object],[object Object],[object Object]

The car that I have chosen is 2008 Saab convertible. The total price with tax is $55,000. My parents will make a down payment of $30,000 and the rest they are going to get a loan from the bank. ,[object Object]

[object Object],Formula Total price of car − down payment = present value.

Now that we have the formula lets solve! ,[object Object],The present value is $25,000

Now, that we know the present value we can find the monthly payments. ,[object Object],How to get into the TMV solver?! This is how…….. 1.) Apps 2.) Finance 3.)TMV Solver

Yes, once again we need to know what everything means…..

N=48 (12 × 4) I%= 8.75 PV= 25,000 ->PMT=(you are trying to find this) FV= 0 P/Y= 12 C/Y= 12 ,[object Object],Your answer should be……… $619.16

[object Object],Formula PMT × N = total amount $619.16 × 48 = $ 29, 719.68 The total loan in 4 years is $29, 719.68
