Q #1: A pharmaceutical company’s stock price was $20.33 on Monday. On Tuesday, the price went up $0.35. On Wednesday, the price decreased from Tuesday’s price by $1.05. On Thursday, the price went up $0.95 from Wednesday’s price. Which of the following was the final price on Thursday?

A. $20.68

B. $19.63

C. $20.63

D. $20.58

Answer Explanation

Thursday’s stock price is found by determining the price of the stock on Tuesday and Wednesday.

Stock price on Monday= $20.33

Stock price on Tuesday= $(20.33+0.35)=$20.68

Stock price on Wednesday =$(20.68-1.05)=$19.63

Stock price on Thursday = $(19.63+0.95)=$20.58

Therefore, the price of the stock on Thursday was $20.58
