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

Q #2: The length of a rectangular room is 9 feet greater than its width. Which of the following equations represents the area (A) of the room?
A. A=9x
B. A=2x+2(x+9)
C. A=x(x+9)
D. A=x+(x+9)
Answer Explanation
we are asked to find the area of the room from the given information.
The first step is to find equation relating the length of the room to its width. If we let the width of the room to be x. Then,
Width of the rectangle= x
Length of rectangle = (x+9)
Area of the rectangle, A= Length*width = (x+9)*x
A=x(x+9)
Therefore, the area of the rectangular room is x(x+9).

Q #3: A person weighed themselves at 190 lb. Three months later they weighed themselves at 180 lb. Which of the following is the percent of weight the person lost over 3 months? (Round to the nearest percent.)
A. 8%
B. 9%
C. 11%
D. 5%
Answer Explanation
Explanation: The percentage change in weight is found in three steps below:
Absolute change in weight = final weight - initial weightAbsolute change in weight = (|180 - 190| = |-10| = 10)
Relative change in weight = (frac{absolute change}{initial weight} = frac{10}{190} = 0.0526)
Percent change = relative change * 100%
Percent change = 0.0526 * 100% = 5.26%
The percent change in weight lost is 5.26%, which is about 5%.

Q #8: Which of the following is the value of x in the equation below. (|2x - 4| - 10 = 2)
A. x=4 or x=-8
B. x=-4 or x=8
C. x=-2 or x=1
D. x=-3 or x=5
Answer Explanation
Explanation:
We need to find the value of x from the given equation. First, we move the value of 10 to the right-hand side of the equation.
Add 10 to both sides of the equation
Next, we apply the absolute rule:
If
, a>0, then u=a or u=-aIn this case a=12, which is greater 0. Then, the first condition becomes
Solving for x
The second condition becomes
Solving for x
Then, the value of x is -4 or 8.
