Ally works in a shop for $18 per hour. She is not allowed to work more than 40 hours a week but has to work at least 20 hours. State a reasonable domain for this problem.

For a given function f(x) we define the domain as the set of possible values of x that we can use in the function.

Here we will find that the domain is D: [20h, 40h]

We know that Ally wins $18 per hour, and she has two restrictions:

She cant' work more than 40 hours.

She needs to work at least 20 hours.

Then her weekly salary can be written as:

s(x) = $18*x

Where x is the number of hours that she works each week.

With the above restrictions we have:

20h ≤ x ≤ 40h

Then the domain is:

D: [20h, 40h]

Hi there!

The domain is:

20<=x<=40

Step-by-step explanation:

This states that:

x>=20

x<=40

Which fits the problem!

Hope this helps

yes

company a
