Question

The following table shows the results when

from a recent survey in which 1500 teens were asked about the most

important inventions of the 20th century. Complete the missing

information.

Answer 1

32% = 480

26% = 390

18% = 270

10% = 150

14% = 210

Explanation:

1500(0.68) = 1020 = 1500 - 1020 = 480

1500(0.74) = 1110 = 1500 - 1110 = 390

1500(0.82) = 1230 = 1500 - 1230 = 270

1500(0.90) = 1350 = 1500 - 1350 = 210

For the last one, just add the percentages off and subtract the number by 100 to see what is left, then do the same with the number of people out of 1500 and that gives you the final number.
