Re: Homework Help Plz

Yeah, when he said 8th grade math I was like "these problems can't possibly take more than 2 steps" so I made bad assumptions =(

But yeah, it's definitely C, 96. Not a bad problem, really...

These look like maybe they come from an AMC 8...they're all that sort of problem =)

EDIT: Height of pyramid, half the side length of the square, and the altitude of a triangle make a 3-4-5 triangle. So the triangles have an altitude of 5 and a base of 6. That gives each triangle an area of 5*6/2 = 15, so with 4 triangles and the 6 x 6 square, the answer is 15 * 4 + 6 * 6 = 96.

Question Four:
Ray's financial institution publishes a list of service charges as shown in the table. (see below) For her first twenty five transactions, she uses Autodebit three times as often as she writes cheques. She also writes as many cheques as she makes cash withdrawals. After his twenty-fifth transaction, she begins to make single transactions. What is the smallest number of transactions he needs to make so that his monthly service charges will exceed the $15.95 'all-in-one' fee?

Service Fee per Item
Cheque $0.50
Autodebit $0.60
Cash Withdrawal $0.45
All-in-one' fee is $ 15.95

A) 29 B) 30 C) 27 D) 28 E) 31

I dont quite understand this one.
sry i couldnt make the chart so well.

Re: Homework Help Plz

ok. so you have 1AD = 3C & 1C = 1CW for the 1st 25.

That is easy. since you have x, x, and 3x, which is 5x. So you have 5 checks, 5 withdrawls, and 15 autodebits. That is $2.50 + $2.25 + $9.00 = $13.75

So $15.95 - $13.75 = $2.20 to go after 25 transactions.

You're looking for the smallest number, so you want to use the most expensive service. That is the autodebit. $2.20 / $.60 = 3 + remainder. So you need to make 4 uses of the autodebit to exceed the $2.20.

So the answer is 25 + 4 = 29. A.

PS - CT (and the FFR Forums in general) are not really the place to ask homework questions. Some of us don't mind helping out once in a while, but as a general rule, we frown upon asking for homework help.

Re: Homework Help Plz

Well if you have someone explain it to you, you could understand the process and steps better so that you know how to work it out the next time you come about these types of problems, right? It would be better if you figure it out on your own because it not only builds your confidence but you also teach yourself how to do something and thats what sticks with you the longest throughout your school years, instead of having to kinda memorize the way someone else did it and applying it to the problem.

Re: Homework Help Plz

Exactly. That's why alot of people at my school fail at maths, they are too busy trying to copy off others and memorise how to do it. Then when we sit for the exam they get all of the basic knowledge section right and fail on the extended section where you have to use your head. This is usually the difference between a C+ B- than a A
