Gavin works two part-time jobs to pay for college. He works 8 hours each week tutoring and 10 hours each week in the dining hall. He gets paid the same hourly wage at each job. His parents also provide Gavin $50 per week for expenses. Gavin writes this expression, 18w+50, where w represents his hourly wage, to represent his total weekly income.

So whats the question. I'm guessing the question is how much money can he can get with a certain number of weeks. Comment this answer below so I can recall it. I believe that the expression is 8hw+10hw+50w. If not then its probably something wrong on my end.

answer: the up tack or falsum is a constant symbol used to represent a logical constant denoting "false" in logic.
