Q #4: A child has a bottle full of pennies, nickels, dimes, and quarters. There are three as many quarters as pennies, five times as many as nickels as pennies, and two times as many dimes as nickels. How many more dimes does the child have than nickels?
A. 4 times as many
B. 5 times as many
C. 2 times as many
D. 10 times as many
Answer 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 = 3x
Number of nickels in the bottle = 5x
Number of dimes in the bottle =2(5x)=10x
Now relating dimes to quarters, we have
Thus, there are 2 times as many dimes as nickels in the box.

Q #10: 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.
