plz help me

r= 2     haha

it costs 23.50 to enter an amusement park and $0.25 to ride a ride. you have $24 write an equation that represents the number of r rides you can ride    

                  24.00 – 23.50                 0.50    

N_rides  =   ————————      =   ———  =   2 rides    

                        0.25                          0.25
