The well formatted two-way frequency table is attached below :
To obtain the number of students aged 15 and above who takes car to school :
From the table given:
• We start by finding the number of students aged 15 and above who takes bus to school :
Under age 15 who takes bus = 60
Let : age 15 and above who takes bus = x
(Under age 15 who takes bus) + (age 15 and above who takes bus) = 110
(60 + x) = 110
x = 110 - 60 = 50
x = 50
(age 15 and above who takes bus) + (age 15 and above who walks/bike) + (age 15 and above who takes car) = 195
Let : age 15 and above who takes car = c
Hence,
(50 + 65 + c) = 195
115 + c = 195
c = 195 - 115
c = 80
Hence, the number of students aged 15 and above who take a car to school is 80
