The number of people that were surveyed are 350 people
The given parameters are:
p = 78% --- the proportion of people that like listening to music in the car
Car =273 --- the number of people for the given proportion
The total number (n) of people surveyed is then calculated as:
Car = p * n
This gives
78% * n = 273
Express 78% as decimal
0.78 * n = 273
Divide both sides by 0.78
n = 350
Hence, 350 people were surveyed
