Solve for the difference between the price of the stocks at the beginning of the day and at the end. 

                                     d = $4.05 - $3.72 = $0.33

Divide this value by the original value of the stocks and multiply by 100% to get the rate of change.

                      ($0.33 / $3.72) x 100% = 8.87%

Thus, the answer is letter A. 8.9%. 

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
