Answer:

The practical domain of the function is [30,32].

Step-by-step explanation:

The given function is

$p(h)=40h-250$

where, p(h) represents the Vonda's weekly pay as a function of hours worked.

She pays a one time $250 chair rental fee, and earns $40 per hour that she works.

Domain is the set of all possible inputs.

The possible domain of the given function is all real numbers but the number of hours can not be negative, therefore h>0.

It is given that Vonda works between 30 and 32 hours per week at a hair salon. So,

$30$

Therefore practical domain of the function is [30,32].
