So we have the two functions:

And we want to find:

This is the same as:

So, to find the answer, find g(1) first:

Now, substitute this value for g(1):

And plug this into f(x):

Therefore:

Answer:
x = 4
Step-by-step explanation:
note the exact value of tan60° = 
Since the triangle is right use the tangent ratio to find x
tan60° =
= 
multiply both sides by x
x ×
= 4
divide both sides by 
x =
= 4 ×
= 4
We can use algebra.
So, what rate time 1.20 = .80
Let x = the rate (in a decimal form)
1.20x = .80
x = .6666666666
Now, we need to multiply by 100 to get a percentage.
66.66 The price is 66% of the regular price.
They marked it off
33.33%
