S=sodas h=hotdogs
228=s+h
s=3h
228=3h+h 228=4h h=57
228=s+57 s=171
Answer: 171 sodas and 57 hotdogs were sold by the vendor
The required value of the given inverse function f⁻¹(22) will be 7.
<h3>What is an inverse function?</h3>
The inverse function is defined as a function obtained by reversing the given function.
Given that f(7) = 22
To determine the value of the given inverse function f⁻¹(22)
An inverse function's main objective is to show the value that occurs in a specific function value. Which means :
If we have f(x) and f⁻¹(x), then
if f(a) = b then f⁻¹(b) = a
As per the given question, we have
⇒ f(7) = 22 then f⁻¹(22) = 7
Therefore, the required value of the given inverse function f⁻¹(22) will be 7.

Answer:
Step-by-step explanation:
f ∝ ghj
Convert the proportion to an equality
f = kghj
Calculate the value of k
18 = k × 4 × 3 × 5
18 = 60k
k = ⅓
Rewrite the equation with the value of k
f = ⅓gkj
Find the new value of f
f =⅓ × 5 × 12 × 3 =
