The solution is as follows:
QUESTION :-
what is the value of x to the nearest whole number?
ANSWER :-

SO
the nearest whole number-->
20.7 --> approximately --> 21 units
Not all info is here. what is the original cost and %off?
Answer:
2,000 miles
Step-by-step explanation:
We are given:

This can be rewritten as:

This is representative of a unit rate, as we have a
in the denominator. To calculate the number of miles in
inches, simply multiply the unit rate by
:


This can rewritten as:

Therefore, there are 2,000 miles in 4 inches.

We can check our solution by simplifying the fraction
by dividing both
and
by
to see if we achieve the unit rate:

Since this is in fact the unit rate, our solution is correct!
