PART A
If 4 pounds = 10 dollars...
4/2 = 2
10/2 = 5
So for 2 pounds, it would cost $5.00
Now for the 1 pound one
4/1 = 4
10/4 = 2.5
For the 1 pound one, it would cost $2.50
PART B
We know that 4 pounds = 10 bucks
Since 1 is 1/10 of 10 (in the cost section), we have to apply this to the pounds section. 4/10 = 0.4. Therefore, $1 = 0.4lb
Now for the last blank...
Since $1 = 0.4, we multiply that by 9. 0.4 x $9 = 3.6lb
