If this ratio is 4:3, then we can write and solve the following equation of ratios:

 4        x + 500
---- = -------------
 3            x

From this we get 4x = 3x + 1500, or x = 1500.

1500 people own flip phones and (1500+500) own cell phones:

1500 people versus 2000 people.

Note that 2000/1500 forms the proper ratio:  4/3.
