_____
The two numbers differ by about 9 orders of magnitude, so the value of the difference between the larger and the smaller is essentially the value of the larger number. The smaller one, by comparison, can be considered to be zero (for subtraction purposes).
Answer:
7.0%
Step-by-step explanation:
Here, we want to get the value of the percentage increase
mathematically, we have the formula for this as follows ;
(new value - old value/old value * 100%
from the question, old value is 8,300 ft and the new value is 8,881 ft
So we have the percentage increase as follows;
(8,881 - 8,300)/8,300 * 100%
= 7.0%
Consider all employees.
A.
- gross pay $32,600 - 100%,
- total job benefits $33,600 - x%.
Then
Employee A receives 3.07% of gross pay in employee benefits.
B.
- gross pay $32,900 - 100%,
- total job benefits $34,000 - x%.
Then
Employee B receives 3.34% of gross pay in employee benefits.
C.
- gross pay $33,400 - 100%,
- total job benefits $33,900 - x%.
Then
Employee C receives 1.50% of gross pay in employee benefits.
D.
- gross pay $33,700 - 100%,
- total job benefits $34,700 - x%.
Then
Employee D receives 2.97% of gross pay in employee benefits.
Answer: correct choice is B.
