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
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
Therefore, the Correct Answer is D.

Q #5: A macaroni and cheese recipe calls for 4/7 cup of flour for every 2 1/5 cup of milk. To make a bigger batch, the chef uses 4 cups of flour. Which of the following would be the amount of milk needed for the bigger batch?
A. 15 1/5 cups
B. 15 2/5
C. 12 8/15 cups
D. 15 cups
Answer Explanation
To find the required number of cups of milk, we need to set up a proportion equation. If we let x be the required number of cups and cups of flour as numerator and cups of milk in denominator, then the result proportion becomes:
We cannot multiply mixed fractions with any number, so we change 2 1/5 into an improper fraction as
The proportion equation becomes
Cross-multiply to solve for x
As a mixed fraction, 77/5 becomes 15 2/5. Therefore, to make a bigger batch, the chef needs 15 2/5 cups of milk.
