Q #1: A baker is using a cookie recipe that call for 3 ¼ cups of flour to yield 30 cookies. How much flour will the baker need to make 16 cookies using the same recipe?
A. 1 11/15 cups
B. 5 8/15 cups
C. 10 13/15 cups
D. 3 ¾ cups
Answer Explanation
Explanation
We are asked to find the number of cups of flour, which requires the concept of proportions.
If we let x to represent the number of cups of flour to make 16 cookies. Then
Solve the value of x by cross-multiplying
Convert the mixed fraction into improper fraction in order to carry out multiplication
The baker needs 26/15 cups of flour needed to make 16 cookies. This is equal to 1 11/15 cups.

Q #2: The American with Disabilities Act (ADA) requires that the slope of a wheelchair ramp be no greater than 1:12. Which of the following is the minimum length of a ramp needed to provide access to a door that is 5.2 feet above the sidewalk?
A. 52 feet
B. 148 feet
C. 32.2 feet
D. 62.4 feet
Answer Explanation
In this problem slope represents the change in height above sidewalk to change in length of the ramp.
From the definition of slope
Letting x to be the minimum length of the ramp, then
Substituting with the known value of slope
Cross-multiply to find the value of x
Thus, the minimum length of the ramp needed is 62.4 feet to access to a door that is 5.2 feet above the sidewalk.

Q #3: 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.
