Respuesta :

Incomplete question. Here's the full question:

At the beginning of the day, the stock market goes up 30 1/2 points. At the end of the day, the stock market goes down 120 1/4 points. What is the total change in the stock market from the beginning of the day to the end of the day?

Answer:

-15%

Step-by-step explanation:

First, we convert the fraction to a whole number;

At the beginning of the day: [tex]30\frac{1}{2}[/tex] = 15 (30*1 / 2)

At the end of the day:  [tex]120\frac{1}{4}[/tex] = 30 (120 * 1 / 4)

Next, since we are told that at the end of the day, the stock market goes down, it means we will subtract any gain it had by the change;

[tex]15-30 = -15%[/tex]%

Hence, the total change in the stock market from the beginning of the day to the end of the​ day is -15%.
