Hi!
Let's write the equation in number form first.
7 over 8
7/8
minus 1
7/8 - 1
over x
7/8 - 1/x
equals 3
7/8 - 1/x = 3
over 4
7/8 - 1/x = 3/4
Now to find the value, let's put each option as the value for x.
A. x = 1
7/8 - 1/1 = 3/4
7/8 - 1 = 3/4
0.875 - 1 = 0.75
-0.125 = 0.75
This is wrong.
B. x = 2
7/8 - 1/2 = 3/4
7/8 - 0.5 = 3/4
0.875 - 0.5 = 0.75
0.375 = 0.75
This is wrong.
C. x = 4
7/8 - 1/4 = 3/4
7/8 - 0.25 = 3/4
0.875 - 0.25 = 0.75
0.625 = 0.75
This is wrong.
D. x = 8
7/8 - 1/8 = 3/4
7/8 - 0.125 = 3/4
0.875 - 0.125 = 0.75
0.75 = 0.75
This is correct!
The answer is d. x = 8
Hope this helps! :)

Answer:
$0.187 per mile
Step-by-step explanation:
The sum of the expenses for the year is ...
$1,187.25 +$118.80 +$300.00 +$75 +$614.80 +$34.90 +$1,780.00
= $4110.75
Then the cost per mile is ...
cost/miles = $4110.75 / 21986 ≈ $0.18697
The cost per mile is about $0.187, or 18.7¢ per mile.

If you need whole cents, that's about $0.19 per mile.
