A person weighed themselves at 176 lb. Four months later they weighed themselves at 186 lb. Which of the following is the percent of weight the person gained over 4 months? (Round to the nearest percent.)
A. 6%
B. 10%
C. 11%
D. 9%
we are asked to find the percent change in weight gain of a person.
First, we need to find the change in weight gained over the 4 months
Change in weight= 186-176=10 lb
The percent change is expressed as change in weight over original weight *100. Then
The percent change in weight is 6% to the nearest whole number.
Therefore, the Correct Answer is A.

Q #1: Simplify the expression above. Which of the following is correct?
A. 6
B. 18
C. 9
D. 22
Answer Explanation
To simplify this expression, we follow the order of operations as follows:
First, we start with the numerator and solve it as follows
[2(6+3*9)]
We start with multiplication in inner brackets, 3 * 9 = 27. The expression becomes
[2(6+27)]
Then, we carry out the addition of 6+27=33. Then, the expression yields
[2(33)]=2*33=66
Now, we solve for denominator, which is 6/2=3.
Thus, the expression is reduced into
The expression reduces into 22.

Q #2: A child has a bottle full of pennies, nickels, dimes, and quarters. There are four as many quarters as pennies, two times as many as nickels as pennies, and seven times as many dimes as nickels. How many more dimes does the child have than nickels?
A. 7 times as many
B. 5 times as many
C. 2 times as many
D. 10 times as many
Answer Explanation
This problem asks us to compare the number of dimes to nickels.
If we let p be number of pennies in the bottle. Then,
Number of quarters in the bottle = 4p
Number of nickels in the bottle = 2p
Number of dimes in the bottle =7(2p)=14p
To find the number of dimes the child has than nickels, we use the ratio:
\(\frac{Dimes}{nickels} =\frac {14p}{2p}\ =\ 7\)
Thus, there are 7 times as many dimes as nickels in the box.

Q #3: A recipe calls for 3.4 teaspoons of milk. 1 teaspoon equals approximately 5 mL. Which of the following is the correct amount of milk in mL?
A. 16.8 mL
B. 17.0 mL
C. 10.5 mL
D. 6.8 mL
Answer Explanation
we are asked to find the amount of milk in mL using the given information.
If we let x represent the amount of milk in mL, we set up a proportion with number of teaspoons on the numerator and amount in mL in the denominator.
A recipe of 3.4 teaspoons is equal to 17.0 mL.
