John took a taxi to work this morning. it cost him $15.50 to drive 5 miles. now it is lunch time and john wants to take another taxi to mcdonald’s. if he receives the same rate, how will it cost him to drive 2 1/2 miles to mcdonald’s

$7.75.

Step-by-step explanation:

This is because 2 and a half, or 2.5, is half of 5.  So that means that the amount would be half as much as the 5 mile amount.  Hope this helps.  :)

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

idk lol xd
