Q #1: Four friends are sharing a pizza. One friend eats half of the pizza. The other three friends equally divide the rest among themselves. What portion of the pizza did each of the other three friends receive?
A. 1/5
B. 1/3
C. ¼
D. 1/6

Q #2: A leather recliner is on sale for 30% less than its original price. A consumer has a coupon that saves an additional of 25% off of the sale price. If the consumer pays $237 for the recliner, which of the following is the original price of the recliner to the nearest dollar?
A. $316
B. $431
C. $451

Answer Explanation
Total percent discount is 30%+25%=55%
So, the percentage of client pays for the recliner is 100%-55%=45%.
The 45% is what represents $237 and the original price is 100%, which is determined as follows:
The original price of the recliner is $526.60 which is approximately $527.

Q #3: (x/y)-z=rw Solve for x in the equation above.
A. X=y(z+rw)
B. X=rw(y-z)
C. X=rwy+z
D. X=rwy-z
Answer Explanation
Given the equation (x/y)-z=rw, we make x the subject of the formula as follows:
(x/y)-z=rw
Add z to both sides of the equation
(x/y)-z+z=rw+z
(x/y)=rw+z
Multiply both sides by y
(x/y)*y=y(rw+z)
X=y(rw+z)
Rearranging the equation results in:
X = y(z+rw)
