Which of the following is the decimal form of 87.5%?
A. 875
B. 8,750
C. 0.875
D. 8.75
The decimal equivalent of the percentage is the percentage value divided by 100. Thus
87.5%=87.5/100=0.875

Q #1: Elevation above sea level and temperature are negatively-correlated variables. Which of the following statement describes the relationship between the variables?
A. As elevation decreases, temperature remains the same
B. As elevation decreases, temperature decreases
C. As elevation increases, temperature decreases
D. As elevation increases, temperature increases
Answer Explanation
In a negatively-correlated variables, a change in one variable result in opposite change in the other variable. In other words, an increase in on variable results in a decrease in the other.
Now let’s analyze the given scenarios:
As elevation decreases, temperature remains the same this is NO-CORRELATION
As elevation decreases, temperature decreases is a POSITIVE CORRELATION
As elevation increases, temperature decreases is a NEGATIVE CORRELATION
As elevation increases, temperature increases is a POSITIVE CORRELATION

Q #2: The force applied is directly proportional to the stretch of a coil. If a force of 132 Newtons stretches a coil 0.07 meters, what force would be needed to stretch a coil 0.1 meter? Round your answer to the nearest tenth.
A. 92.4 Newtons
B. 1885.7 Newtons
C. 188.6 Newtons
D. 136.0 Newtons
Answer Explanation
In direct proportion relation, we utilize the relationship as:
Variable∝
Variable 2Thus from the given case,
Force∝
stretchWe introduce a constant term, K to remove the sign of proportionality as
Force=K* stretch
Let’s find the value of K, using Force=132 N and stretch of 0.07 m
132 N=K*0.07 m
K=132 N/0.07 m=1885.7 N/m
Now substitute this value of K in the following equation
Force=1885.7 N/m * stretch
For a stretch of 0.1 m, the force needed is
Force=1885.7 N/m * 0.1 m=188.57 N=188.6 N

Q #3: 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
D. $527
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.
