The two way table shows the number of students who bring their lunch to school or who bus

Step-by-step explanation:

Given is a two way table with rows representing lunch and columns representing riding bus.

The row is divided as ride bus and do not ride bus and column as bring lunch and do not bring lunch.

We find from the table the total number of students who bring lunch =

I column total = 95

The total number of students who ride bus = I row total = 75

Difference = 95-75 =20

Hence 20 more students bring lunch than students who ride bus

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
