Marco owed his father $250 and began paying him back $20 at the end of each week, beginning November 1st. Joni owed her father $150 and began paying back $10 at the end of each week, beginning on the same day. What Marco owed his father in dollars at the end if n weeks can be represented by f(n) = 250 - 20n. What Joni owed her father in dollars at the end of n weeks can be represented by g(n) = 150 - 10n.
