Answer: 2/3 or .667
Step-by-step explanation:
The inverse of f(x) would be f(x) = 2
- 8.
We can find this by taking the original equation and switching the x and f(x). Once we do this, we solve for the f(x) in its new place and that is the inverse equation. It is taken step by step for you below.
Take the original.
f(x) = 
Now switch the x and f(x)
x = 
Now square both sides.
=
f(x) + 4
Now subtract 4 from both sides.
- 4 =
f(x)
Now multiply both sides by 2.
2
- 8 = f(x)
And once you've returned to f(x) =, then you have your inverse.
Total number of pairs = 24 pairs.
Total cost of 24 pairs = $800 approximately.
Cost of each pair = 
Plugging values in the above formula, we get
Cost of each pair = 
If we divide 800 by 24, we get 33.33 approximately.
But in the given problem, estimated cost is given $28 per pair.
If we subtract 33.33-28, we get $5.33.
So, the estimated cost is $5.33 each pair less than the actual cost of each pair.
Therefore, $28 per pair is not a good estimate of the price.
