Answer:
The sum is 1575.
Step-by-step explanation:
Consider the provided information.
It is given that positive integers smaller than 1000 and that can be written in the form 
Where n is integer that means the value of n can be a positive number or a negative number.
For n = 0

For n=-1

For n=-2

For n = -3 the obtained number is not an integer.
Now consider the positive value of n.
For n=1

For n=2

For n=3

For n=4 the obtained number is greater than 1000.
Now add all the numbers.

Hence, the sum is 1575.
The answer should be C. By combining like terms you can find the answer. 1.75a+2.75a = 4.5a
2.25b + 1.75b = 4b
2.25c + 1.25c = 3.5c
