Im having a hard time setting up the equations for both statements, can anyone please help....thanks a tons :) For each customer, a bakery charges p dollars for the 1st loaf of bread bought by the customer and charges q dollars for each additional loaf bought by the customer. What is the value of p?...

I am still a bit confused. Statement 1 says "customer who buys 2 loafs is charged 10% less per loaf" so to me that sounds like:

p+q=0.90(p+q/2)

how did you have price per loaf i.e. p+q/2=9/10p?

Can anyone please share there methods for this question. Greatly appreciated : ) The sum of integers in list S is the s...

Try plugging in numbers of statement 1. I used 1,-3,6,-6 and got No's for all of them i.e n-1 is not divisible by 3, thus answer is A. You are right abt the 2nd statement.

I hope this helps

Awesome : ) this is a much efficient way of doing it. Thanks alot man i really appreciate all your help.

Sorry about my last post, U are right n-1 is divisible by 3. Here's how i did it (The plug-in technique is something i learned at Princeton, so i will try to explain it as much as i can). Statement 1 says that n^2+n is not divisible by 3. Now they way i do it is by plugging in numbers. Let try the f...

In the xy-plane, point (r,s) lies on a circle with centre at origin. What is the value of r^2+s^2? 1) Radius=2 2) The point sqrt2,-sqrt 2 lies on the circle. Answer is D. Im an a little confused about statement 2. How does sqrt2,-sqrt 2 represent (r,s)? It just says that its another point lying on t...
