Answer :
For 8 packs - $32
For 20 packs - $80
Explanation:
Given :
12 packs = $48
Finding the cost of one pack of juice box :-
If 12 packs = $48
1 pack = 48/12 = $4
So, One pack of juice box is $4.
Finding the cost of 8 pack of juice boxes :-
If 1 pack - $4
8 packs = 8 x 4 = $32.
she will pay $32 to buy 8 more packs of juice boxes at the same store.
Total packs = 12 + 8 = 20 packs
If 8 packs = $32
20 packs = (20x32)/8
=> 640/8
=> $80.
She will pay total $80 to buy 20 pack of juice boxes.
