Respuesta :

add all teens at Saturday which is 41 and divide it by 90 which is 0.45reapeated and move it 2 decimal places to the left to get 46 rounded
the 4th survey is biased since its data is far different from the others.

the total number of people surveyed is 90, the total number of people who prefer hanging out on Saturday is 41, so 41/90= 0.456 (.46)
.46 x 100 = 46% of people prefer to hang out Saturday
