@Matt: Awesome approach.

Exactly. That was the problem i was having. I solved it with your approach by testing values and looking that the remaining cost must be divisible by 0.5. However, i wanted to make the algebraic equation but was unable to do so.

Step 1: Plot both points on the graph and connect the points to the x-axis to form a right angle triangle Step 2: A right angled triangle is formed with two sides of length 3. The third side can be found using Pythagorean Theorem. 3^2 + 3^2 = x^2. Therefore, x(radius) = √18 Step 3: Area of circle ...

So we have to write the equation in terms of the constant: for example the equation would be: p + k = r, r + k = s. But you have written in the TERMS of constant because when you will test the statements below, you can check that whether the sequence continues in TERMS of the constant. The constant ...

A bar over

A bar over a sequence of digits in a decimal indicates that the sequence repeats indefinitely. What is the value of (10^4 - 10^2) (0.0012)?

Note: There is a bar over "12" in 0.0012. Couldn't figure out how to insert it.

(A) 0
(B) 0.12 (with the bar on 12)
(C) 1.2
(D) 10
(E) 12
