At the beginning of the day the stock market goes down 50 1/2 points and stays at this level for most of the day. At the end of the day the stock market goes up 80 1/4 points from the low at the beginning of the day. What is the total change in the stock market from the beginning of the day to the end of the day?

Step-by-step explanation:

In this problem, we are expected to calculate the change in the price of a particular stock

Given that the days high is 80 1/4

and also that the days low is 50 1/2

we can calculate the change by subtracting the days low from the days high

i.e 80 1/4- 50 1/2= 321/4-101/2= (321-202)/4= 119/4 = 29 3/4

hence the change for the day is 29 3/4

Also we can calculate the percentage change as

%change = (high-low)/low*100

%change= 80 1/4- 50 1/2/50 1/2= 29 3/4/50 1/2 *100

%change= 119/4*2/101 *100= 119/202*100= 0.589*100= 58.9%

%change= 58.9%
