Rachels pay for T hours is given by the function r(t)=11T, where 20 is less than or equal to T, is Less than or equal to 30. Find the domain and range for each function. Compare their hourly wages and the amount they earn per week.
I don't know how to type on here 20 is less than or equal to T and T is less than or equal to 30. It should look something like this but there is suppose to be a line under the less than sign. 20 < T <30

Jan: \ =\ 12t\ \forall\ t\ \in\ \mathbb{R}\ |\ 30\ \leq\ t\ \leq\ 40)
. Hence \ \leq\ 480\ \forall\ t\ \in\ \mathbb{R}\ |\ 30\ \leq\ t\ \leq\ 40)
.
Rachel: \ =\ 11t\ \forall\ t\ \in\ \mathbb{R}\ |\ 20\ \leq\ t\ \leq\ 30)
. Hence \ \leq\ 330\ \forall\ t\ \in\ \mathbb{R}\ |\ 20\ \leq\ t\ \leq\ 30)
