### Example Question #61 : Algebraic Concepts

In June, a company had a profit of million. In July, the company doubled that profit. In August, the company's profits rose by percent. If profits rise by another percent in September, what is the September profit?

**Possible Answers:**

million

million

million

million

million

**Correct answer:**

million

The profit in July is twice the profit in June, or $6 million.

Because profits rise by 15% in August, August's profit is really 115% of July's profit:

Similarly, September's profit is 115% of August's profit:

### Example Question #745 : Isee Upper Level (Grades 9 12) Quantitative Reasoning

Column A Column B

**Possible Answers:**

The quantity in Column B is greater.

The realtionship between the columns cannnot be determined.

The quantities in both columns are equal.

The quantity in Column A is greater.

**Correct answer:**

The quantities in both columns are equal.

and mean that you must plug in what it's inside the parantheses to x in the function. Therefore, when you plug in -2 to the function, you get , which is 11. Then, plug in 2 to the function, which gives you , which is also 11. Therefore, the columns are equal.

### Example Question #62 : How To Find The Solution To An Equation

Column A Column B

The slope of The slope of

the line the line perpendicular

. to the line in Column A.

**Possible Answers:**

The quantity in Column B is greater.

The quantity in Column A is greater.

The quantities are equal.

There can be do relationship determined.

**Correct answer:**

The quantity in Column A is greater.

The slope of the line is 4. You can determine this by remembering the y=mx+b slope-intercept form. "M" is slope, so the number in front of x is the slope. Therefore, it's 4. The slope of a line perpendicular to the line is the negative reciprocal of the first slope. Therefore, if the slope of the first line is 4, then the slope of the perpendicular line is . Therefore, Column A is greater.
