Q #1: Simplify the expression above. Which of the following is correct?
A. 33
B. 44
C. 25
D. 12
Answer Explanation
Let's simplify the expression step by step:
Step 1: Inside the square brackets, perform the operation within parentheses first:
([4(3+6?5)]=[4(3+30)] )
Step 2: Continue simplifying inside the square brackets:
([4(3+30)]=[4ast33])
Step 3: Calculate the value inside the square brackets:
([4ast33]=132)
Step 4: Now, deal with the denominator:
((20÷5)=4)
Step 5: Finally, divide the result from step 3 by the result from step 4:
(132/4=33)
So, the simplified expression is 33.

Q #2: 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%.
