Answer:
Domain![=\{1,2,3,4,5,6,7,8,9,10,11,12,,13,14,15,16,17,18,19,20\}](https://tex.z-dn.net/?f=%3D%5C%7B1%2C2%2C3%2C4%2C5%2C6%2C7%2C8%2C9%2C10%2C11%2C12%2C%2C13%2C14%2C15%2C16%2C17%2C18%2C19%2C20%5C%7D)
In other words Domain![=\{x|x\ is\ an\ integer\ and\ 1\leq x\leq20\}](https://tex.z-dn.net/?f=%3D%5C%7Bx%7Cx%5C%20is%5C%20an%5C%20integer%5C%20and%5C%201%5Cleq%20x%5Cleq20%5C%7D)
Step-by-step explanation:
![C(x)=80-4x](https://tex.z-dn.net/?f=C%28x%29%3D80-4x)
Let after
weeks she has left no money.
![c(t)=0\\80-4t=0\\4t=80\\t=20](https://tex.z-dn.net/?f=c%28t%29%3D0%5C%5C80-4t%3D0%5C%5C4t%3D80%5C%5Ct%3D20)
That means she can have money for ice cream from the week 1 to week 20 and after that she will have no money.
So
can be any number between
and ![20](https://tex.z-dn.net/?f=20)
Hence Domain![=\{x|x\ is\ an\ integer\ and\ 1\leq x\leq20\}](https://tex.z-dn.net/?f=%3D%5C%7Bx%7Cx%5C%20is%5C%20an%5C%20integer%5C%20and%5C%201%5Cleq%20x%5Cleq20%5C%7D)
