Which is the constant of proportionality for the data in the table?

a
18

b
2

c
6

d
12

C) 6

Step-by-step explanation:

From the given data we can find the constant of proportionality by dividing The number of people by number of cars.

Constant of proportionality =

Taking any point from the table will give the same constant of proportionality as they are proportional quantities.

Constant of proportionality =

This can be written as 6 people per car.

For 10 cars, number of people will be ==60 people.

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
