Jonathan tries to mathematically model the number of seats in a given row. He tries to come up with an equation for the number of seats and determines: S = 7+2, where S is the number of seats in row, r Does this equation work for r=1? What about for r = 2 and r = 3? Show calculations that support your yes/no answers The correct equation is S = 2r +7 Venly this equation matches your table for r=1, r=2, and >=3.
