Tori has a cell phone plan that charges $0.09 for each text message sent. Tori plans to spend no more than $40 per month on her
texting bill. If c(t)=0.09t represents the total phone bill based on the number of texts (t) that tori sends each month, what is the domain of the function?
She can send 444 messages per month because 40 divided by. 09 is 444.4444444 but you can't message 444.4444444 so you can only message the 444 because that's the most you can do possible.
