Question

On a car trip , the number of miles driven , m , is proportional to the number of gallons of gas used , g , as shown in the table

Answer 1

m = 32g

Explanation:

The proportion between m and g can be written ...

m = kg

where k is the constant of proportionality.

__

We can find its value by dividing by g:

k = m/g

Using any pair of corresponding values from the table, we find ...

k = 64/2 = 32

The relationship between m and g can be expressed by the equation ...

m = 32g
