Peter played his favorite video game for 10 hours last week. Today, Peter's parents restricted him to 5 additional hours each week for the next 8 weeks. Create the function, f(x), that models Peter's total video game time?

Question

Is it f(x)=5x + 10 or f(x)=5x + 8 or f(x)=5x. Those are the answers I could think of. Not sure about it though.

Answer 1

Peter has already played 10 hours.

Assuming that Peter does play 5 hours, without failure, every week.

f(x)=5x+10 is the answer (where x is the week no. — first week, second week, etc.)
