Answer:
She would save $2
Step-by-step explanation:
   We can solve how much 144 sodas will cost in each place, and then compare the difference between them.
   [Solving]
   144 sodas are needed in total.
   Price Co is 36 diet sodas for 10 dollars.
-> 144 / 36 = 4
-> 4 * $10 = $40 at Price Co
   Save More is 24 diet sodas for 7 dollars.
-> 144 / 24 = 6
-> 6 * $7 = $42 at Save More
   [Compare differences]
$42 - $40 = $2
-> She would save $2 by purchasing the drinks at Price Co.
