Answer 3

Total people surveyed = 10 + 12 + 16 + 7 + 15 + 8 = 58

Answer 4

Surveyed that prefer plan A = 10 + 12 + 16

Answer 5

Surveyed that in 40-49 age group = 16 + 8

Answer 6

All together that's 10 + 12 + 16 + 16 + 8
And we should subtract anything we counted twice
= 10 + 12 + 16 + 8

out of the total people surveyed
46 / 58

46 / 58 = 0.793
Uh oh that's not an option XD lemme check again
