You decide you will buy a stock only if it shows an overall increase over the next 30 days. The

first 10 days it has an average daily increase of $0.30. The next 10 days it has an average daily
decrease of $0.45. The last 10 days it has an average daily increase of $0.25. Will you buy the
stock? Explain.

0.3 - 0.45 + 0.24 = ?

0.09 is the answer for the question

To determine whether you should buy the stock, you need to calculate the overall change in stock price over the 30-day period.

First, let's find the net change in price for each 10-day period:

1. For the first 10 days: Since the average daily increase is $0.30, the net change over 10 days would be 10 * $0.30 = $3.00 increase.

2. For the next 10 days: The average daily decrease is $0.45, so the net change over this period would be 10 * -$0.45 = -$4.50 decrease.

3. For the last 10 days: With an average daily increase of $0.25, the net change would be 10 * $0.25 = $2.50 increase.

Next, let's calculate the overall change in price. We need to sum up the net changes from each 10-day period:

Net change = $3.00 (first 10 days) - $4.50 (next 10 days) + $2.50 (last 10 days) = $1.00 increase over the 30-day period.

Since the overall change in price is positive ($1.00 increase), you should buy the stock as it shows an overall increase over the next 30 days.
