Final answer:
The stock's value at the end of the day is found by subtracting the decrease from the initial value: 58¼ (starting value) minus 3⅛ (decrease) equals 54⅛ or 54.625 in decimal.
Step-by-step explanation:
The student is asking to calculate the new value of a stock after it decreased during the day. The stock began the day at 58¼, which is 58.25 when converted to decimal form. During the day, the value went down by 3⅛, which is 3.625 in decimal form. To find the stock's value at the end of the day, we simply subtract the decrease from the initial value:
58.25 (initial value) - 3.625 (decrease) = 54.625 (end of day value)
Therefore, the value of the stock at the end of the day was 54⅛ or 54.625 in decimal form.
