Question

Quizplus · Accepted Answer

To find the increase or decrease, we subtract the second day's price from the first day's price:

42.19 - 41.31 = 0.88

Since the stock price increased, the answer cannot be A or B.

To find the percent increase, we divide the increase by the original price, then multiply by 100:

(0.88/41.31) * 100 = 2.13%

Rounded to the nearest tenth of a percent, the answer is 2.1%.

Only choice C has the correct sign for the increase/decrease and the correct value for the percent increase. The decrease in the stock price is 0.88 (42.19-41.31) and the percent decrease is (0.88/42.19)*100 = 2.086% which rounds to 2.1%, both of which are given in option C.
