A because 3 is rational, and it’s a natural and whole number because it’s about 0. It’s an integer because integers include negative and positive numbers.
Given:


To find:
The value of
.
Solution:
We have,
![[\because d(t)=80t]](https://tex.z-dn.net/?f=%5B%5Cbecause%20d%28t%29%3D80t%5D)

Now,
![[\because C(d)=0.09d]](https://tex.z-dn.net/?f=%5B%5Cbecause%20C%28d%29%3D0.09d%5D)

Therefore, the value of
is 72.
Find 6% of 3,500 and 4% of 4,000 then subtract the two
Parallel lines run along side of each other, but never intersect.
-----------------------
<== these are parallel lines...they never cross

N equals 1.428 If you are supposed to round, you could put 1.43.
