A child has a bottle full of pennies, nickels, dimes, and quarters. There are four as many quarters as pennies, three times as many as nickels as pennies, and five times as many dimes as nickels. How many more dimes does the child have than pennies?
A. 5 times as many
B. 10 times as many
C. 20 times as many
D. 15 times as many
Explanation:
In this question, we need to find the ratio of dimes to quarters.
If we let x be number of pennies in the bottle. Then,
Number of quarters in the bottle = 4x
Number of nickels in the bottle = 3x
Number of dimes in the bottle =5(3x)=15x
Now relating dimes to quarters, we have
Thus, there are 15 times as many dimes as pennies in the box.
Therefore, the Correct Answer is D.

Q #2: The data below represents students’ test scores. Which of the following is the median of the set data? 80, 76, 92, 96, 44, 86, 56, 93, 69
A. 86
B. 69
C. 44
D. 80
Answer Explanation
Explanation: the median of a data set is the element that is found on the middle position.
To find median, organize the given data from the smallest to largest.
44, 56, 69, 76, 80, 86, 92, 93, 96
Now, the number of elements in the date set is 9, which is an odd number. The median falls in the position
(N+1)/2=(9+1)/2=10/2=5.
The number that falls in the 5th position is 80. Thus, 80 is the median of the data.
