Question

A particular stock, initially worth 16 points, loses 2 points every hour for 6 hours. How many points is the stock worth after 6 hours?

A. -13 points
B. -2 points
C. 2 points
D. 13 points

Answer 1

The stock is worth 4 points after 6 hours.

Step-by-step explanation:

After 6 hours, the stock loses 2 points every hour for a total of 6 hours. So, the total decrease in points is 2 points/hour * 6 hours = 12 points. Starting from the initial worth of 16 points, we subtract the total decrease to find the final value: 16 points - 12 points = 4 points.

Answer 2

The stock is worth 4 points after 6 hours.

Step-by-step explanation:

The stock starts at 16 points and loses 2 points every hour for 6 hours. To find the final value, you multiply the rate of decrease (2 points per hour) by the number of hours (6 hours) and subtract this from the initial value:

Initial Value - (Rate × Time) = 16 - (2 × 6) = 16 - 12 = 4

Therefore, the stock is worth 4 points after 6 hours. The correct answer is not provided in the options given (A, B, C, D). If you were to choose the closest option, it would be option C (2 points), but the accurate answer is 4 points based on the calculation.

This type of problem involves basic arithmetic, where understanding the rate of change and applying it over a given period leads to the correct solution. It's important to recognize the relationship between the initial value, rate, and time in such problems to make accurate calculations.
