Answer:
$1.44
Step-by-step explanation:
Store A:
12 bottles of water for $3.36
Then
48 bottles of water for [tex]\$3.36\cdot 4=\$13.44[/tex] (48 bottles is 4 times greater than 12 bottles)
Store B:
24 bottles of water for $6.00
Then
48 bottles of water for [tex]\$6.00\cdot 2=\$12[/tex] (48 bottles is twice greater than 24 bottles)
Difference:
[tex]\$13.44-\$12=\$1.44[/tex]
