Answer:
B.
21---------------->7
24--------------->8
27--------------->9
Explanation:
Since there are 21 cheesecakes for every 7 blocks of cream cheese, we can set up the an equation
So that means there are 3 cheesecakes for every block of cream cheese
So we can create a table
3----------------->1
6------------------>2
9----------------->3
12---------------->4
15---------------->5
18---------------->6
21---------------->7
24--------------->8
27--------------->9
The equation would be:
y = 3x
21 = 3(7)
