(Refer the attachment)
So 4 pounds corresponds to 22 dollars.
the proportion is,
4:22
=1:22/4
i.e 1 pound corresponds to 22/4 dollars
1 pound =22/4
1 pound of cherry=5.5 dollars
Similar for 2 pounds
2pounds = 2*(22/4)
=2*5.5
=11 dollars
Now for 3 pounds
3 pounds =3*(22/4)
=3*5.5
=16.5 dollars.
The second number line will be allocated the points for 1,2 and 3 pounds of cherries as 5.5,11,16.5 respectively.
