Based on recent statistics one airline expects that 42 of it

Based on recent statistics, one airline expects that 4.2% of its customers will be \"no-shows.\" If the airline sold 260 seats, how many people would the airline expect as no-shows? Round to the nearest whole unit. In a survey of college students, 58% said that they wore their seat belts regularly. If this represents 493 people, how many people were surveyed? Victoria spends $720 per month on rent. If her monthly take-home pay is $1800, what percent does she pay in rent? Round to the nearest whole percent.

Solution

57) People the airline would expect as no shows = 4.2% of 260

= 10.92

= 11 (after rounding off)

11 people the air line would expect as no shows

--------------------------------------------

58) 58% is equivalent to 493 people

Hence 100% is equivalent to 49300/58 = 850

Hence 850 people were surveyed

---------------------------

59) For take home pay 1800, rent = 720

Percentage of rent = 720/1800% = 40%
