Math Problem Statement
Solution
To find the value of the stock at the end of the day on Friday, we need to start with the initial value on Monday and then apply each day's change in stock value sequentially.
The initial value on Monday is $37.69.
Here's the breakdown for each day:
-
Tuesday: Add $0.69
-
Wednesday: Subtract $0.82
-
Thursday: Add $0.37
-
Friday: Subtract $0.14
So, the value of the stock at the end of the day on Friday is $37.79.
The correct answer is:
- C. $37.79

Here are five related questions to expand your understanding:
- How would the calculation change if there was an additional day with a stock decrease?
- What would the stock price be if Friday’s change was positive instead of negative?
- If the stock’s value had started at $40 instead of $37.69, what would the ending value be?
- How could you calculate the overall change in stock value across the week in one step?
- What if there was a cumulative percentage increase each day instead of fixed amounts?
Tip: When working with sequential changes, apply each change one at a time to track cumulative values accurately.
