Answer:
T(h) = 20 + 40h
Step-by-step explanation:
Alright, so let's start off.
No matter how many hours a person gets tutored for, there's always the $20 as a baseline for study materials. So, the $20 MUST be included in our equation, which looks like this for now:
T(h) = 20
Every hour, $40 is added onto the expense.
For example, if a person was tutored for two hours, it would cost them $20 + 2(40) = $100.
This can be signified in the equation as
T(h) = 20 + 40h
And, that's your equation! :)
