Jesse Farley · Answer 1

10.25 + 2.00 = 12.25 ... cost of pizza and soda

12.25 - 1.50x = 4.75 ... with x being the number of touchdowns

-1.50x = 4.75 - 12.25 ... I subtracted 12.25 from both sides

-1.50x = - 7.50 ... now divide both sides by - 1.50

x = - 7.50 / - 1.50

x = 6 ... They would have to score 6 touchdowns
